Autosomal dominant myopathy with proximal weakness and early respiratory muscle involvement maps to chromosome 2q. (1/966)

Two Swedish families with autosomal dominant myopathy, who also had proximal weakness, early respiratory failure, and characteristic cytoplasmic bodies in the affected muscle biopsies, were screened for linkage by means of the human genome screening set (Cooperative Human Linkage Center Human Screening Set/Weber version 6). Most chromosome regions were completely excluded by linkage analysis (LOD score <-2). Linkage to the chromosomal region 2q24-q31 was established. A maximum combined two-point LOD score of 4.87 at a recombination fraction of 0 was obtained with marker D2S1245. Haplotype analysis indicated that the gene responsible for the disease is likely to be located in the 17-cM region between markers D2S2384 and D2S364. The affected individuals from these two families share an identical haplotype, which suggests a common origin.  (+info)

Subcellular adaptation of the human diaphragm in chronic obstructive pulmonary disease. (2/966)

Pulmonary hyperinflation impairs the function of the diaphragm in patients with chronic obstructive pulmonary disease (COPD). However, it has been recently demonstrated that the muscle can counterbalance this deleterious effect, remodelling its structure (i.e. changing the proportion of different types of fibres). The aim of this study was to investigate whether the functional impairment present in COPD patients can be associated with structural subcellular changes of the diaphragm. Twenty individuals (60+/-9 yrs, 11 COPD patients and 9 subjects with normal spirometry) undergoing thoracotomy were included. Nutritional status and respiratory function were evaluated prior to surgery. Then, small samples of the costal diaphragm were obtained and processed for electron microscopy analysis. COPD patients showed a mean forced expiratory volume in one second (FEV1) of 60+/-9% predicted, a higher concentration of mitochondria (n(mit)) in their diaphragm than controls (0.62+/-0.16 versus 0.46+/-0.16 mitochondrial transections (mt) x microm(-2), p<0.05). On the other hand, subjects with air trapping (residual volume (RV)/total lung capacity (TLC) >37%) disclosed not only a higher n(mit) (0.63+/-0.17 versus 0.43+/-0.07 mt x microm(-2), p<0.05) but shorter sarcomeres (L(sar)) than subjects without this functional abnormality (2.08+/-0.16 to 2.27+/-0.15 microm, p<0.05). Glycogen stores were similar in COPD and controls. The severity of airways obstruction (i.e. FEV1) was associated with n(mit) (r=-0.555, p=0.01), while the amount of air trapping (i.e. RV/TLC) was found to correlate with both n(mit) (r=0.631, p=0.005) and L(sar) (r=-0.526, p<0.05). Finally, maximal inspiratory pressure (PI,max) inversely correlated with n(mit) (r=-0.547, p=0.01). In conclusion, impairment in lung function occurring in patients with chronic obstructive pulmonary disease is associated with subcellular changes in their diaphragm, namely a shortening in the length of sarcomeres and an increase in the concentration of mitochondria. These changes form a part of muscle remodelling, probably contributing to a better functional muscle behaviour.  (+info)

Long-term recovery of diaphragm strength in neuralgic amyotrophy. (3/966)

Diaphragm paralysis is a recognized complication of neuralgic amyotrophy that causes severe dyspnoea. Although recovery of strength in the arm muscles, when affected, is common, there are little data on recovery of diaphragm function. This study, therefore, re-assessed diaphragm strength in cases of bilateral diaphragm paralysis due to neuralgic amyotrophy that had previously been diagnosed at the authors institutions. Fourteen patients were recalled between 2 and 11 yrs after the original diagnosis. Respiratory muscle and diaphragm strength were measured by volitional manoeuvres as maximal inspiratory pressure and sniff transdiaphragmatic pressure. Cervical magnetic phrenic nerve stimulation was used to give a nonvolitional measure of diaphragm strength: twitch transdiaphragmatic pressure. Only two patients remained severely breathless. Ten of the 14 patients had evidence of some recovery of diaphragm strength, in seven cases to within 50% of the lower limit of normal. The rate of recovery was variable: one patient had some recovery after 2 yrs, and the rest took 3 yrs or more. In conclusion, in most patients with diaphragm paralysis due to neuralgic amyotrophy, some recovery of the diaphragm strength occurs, but the rate of recovery may be slow.  (+info)

Respiratory muscle involvement in multiple sclerosis. (4/966)

Respiratory complications are common in the terminal stages of multiple sclerosis and contribute to mortality in these patients. When respiratory motor pathways are involved, respiratory muscle weakness frequently occurs. Although it is well established that weakness of the respiratory muscles produces a restrictive ventilatory defect, the degree of muscle weakness and pulmonary function are poorly related. Respiratory muscle weakness was observed in patients with normal or near normal pulmonary function. Expiratory muscle weakness is more prominent than inspiratory muscle weakness and may impair performance of coughing. Subsequently, in addition to bulbar dysfunction, respiratory muscle weakness may contribute to ineffective coughing, pneumonia, and sometimes even acute ventilatory failure may ensue. Respiratory muscle weakness may also occur early in the course of the disease. Recent studies suggest that the respiratory muscles can be trained for both strength and endurance in multiple sclerosis patients. Whether respiratory muscle training delays the development of respiratory dysfunction and subsequently improves exercise capacity and cough efficacy, prevents pulmonary complications or prolongs survival in the long-term remains to be determined.  (+info)

Breathing responses to small inspiratory threshold loads in humans. (5/966)

To investiage the effect of inspiratory threshold load (ITL) on breathing, all previous work studied loads that were much greater than would be encountered under pathophysiological conditions. We hypothesized that mild ITL from 2.5 to 20 cmH2O is sufficient to modify control and sensation of breathing. The study was performed in healthy subjects. The results demonstrated that with mild ITL 1) inspiratory difficulty sensation could be perceived at an ITL of 2.5 cmH2O; 2) tidal volume increased without change in breathing frequency, resulting in hyperpnea; and 3) although additional time was required for inspiratory pressure to attain the threshold before inspiratory flow was initiated, the total inspiratory muscle contraction time remained constant. This resulted in shortening of the available time for inspiratory flow, so that the tidal volume was maintained or increased by significant increase in mean inspiratory flow. On the basis of computer simulation, we conclude that the mild ITL is sufficient to increase breathing sensation and alter breathing control, presumably aiming at maintaining a certain level of ventilation but minimizing the energy consumption of the inspiratory muscles.  (+info)

Influence of central antitussive drugs on the cough motor pattern. (6/966)

The present study was conducted to determine the effects of administration of centrally active antitussive drugs on the cough motor pattern. Electromyograms of diaphragm and rectus abdominis muscles were recorded in anesthetized, spontaneously breathing cats. Cough was produced by mechanical stimulation of the intrathoracic trachea. Centrally acting drugs administered included codeine, morphine, dextromethorphan, baclofen, CP-99,994, and SR-48,968. Intravertebral artery administration of all drugs reduced cough number (number of coughs per stimulus trial) and rectus abdominis burst amplitude in a dose-dependent manner. Codeine, dextromethorphan, CP-99,994, SR-48,968, and baclofen had no effect on cough cycle timing (CTtot) or diaphragm amplitude during cough, even at doses that inhibited cough number by 80-90%. Morphine lengthened CTtot and inhibited diaphragm amplitude during cough, but these effects were not dose dependent. Only CP-99,994 altered the eupneic respiratory pattern. Central antitussive drugs primarily suppress cough by inhibition of expiratory motor drive and cough number. CTtot and inspiratory motor drive are relatively insensitive to the effects of these drugs. CTtot can be controlled independently from cough number.  (+info)

Early occurrence of respiratory muscle deoxygenation assessed by near-infrared spectroscopy during leg exercise in patients with chronic heart failure. (7/966)

The mechanisms of respiratory muscle deoxygenation during incremental leg exercise with expired gas analysis were investigated in 29 patients with chronic heart failure and 21 normal subjects. The deoxygenation and blood volume of the respiratory muscle and exercising leg muscle were assessed by near-infrared spectroscopy (NIRS). To evaluate the influence of the leg exercise on the blood volume of the respiratory muscle, 10 normal subjects also underwent a hyperventilation test with NIRS. The respiratory muscle deoxygenation point (RDP), at which oxygenated hemoglobin starts to decrease, was observed in both groups during exercise. The oxygen consumption (VO2) and the minute ventilation at the RDP in the patients was lower (p<0.01). At the same VO2, the respiratory rate was higher in patients (p<0.01). During exercise, the blood volume of the leg muscle increased, while that of the respiratory muscle decreased. During a hyperventilation test, the minute ventilation was higher than that of the RDP during exercise, the blood volume of the respiratory muscle did not decrease, and the RDP was not detectable. In conclusion, a limited ability to increase perfusion of respiratory muscles during exercise combined with the greater work of breathing results in early respiratory muscle deoxygenation in patients with chronic heart failure.  (+info)

Contribution of lung function to exercise capacity in patients with chronic heart failure. (8/966)

BACKGROUND: The importance of exercise capacity as an indicator of prognosis in patients with heart disease is well recognized. However, factors contributing to exercise limitation in such patients have not been fully characterized and in particular, the role of lung function in determining exercise capacity has not been extensively investigated. OBJECTIVE: To examine the extent to which pulmonary function and respiratory muscle strength indices predict exercise performance in patients with moderate to severe heart failure. METHODS: Fifty stable heart failure patients underwent a maximal symptom-limited cardiopulmonary exercise test on a treadmill to determine maximum oxygen consumption (VO2max), pulmonary function tests and maximum inspiratory (PImax) and expiratory (PEmax) pressure measurement. RESULTS: In univariate analysis, VO2max correlated with forced vital capacity (r = 0.35, p = 0.01), forced expiratory volume in 1 s (r = 0.45, p = 0.001), FEV1/FVC ratio (r = 0.37, p = 0.009), maximal midexpiratory flow rate (FEF25-75, r = 0. 47, p < 0.001), and PImax (r = 0.46, p = 0.001), but not with total lung capacity, diffusion capacity or PEmax. In stepwise linear regression analysis, FEF25-75 and PImax were shown to be independently related to VO2max, with a combined r and r2 value of 0. 56 and 0.32, respectively. CONCLUSIONS: Lung function indices overall accounted for only approximately 30% of the variance in maximum exercise capacity observed in heart failure patients. The mechanism(s) by which these variables could set exercise limitation in heart failure awaits further investigation.  (+info)

AIM: The aim of this study was to examine the changes of maximal inspiratory mouth pressure (PImax) during a 400-m front crawl swimming trial. METHODS: Eleven well-trained competitive swimmers (age: 17.6+/-0.8 years, mean+/-SE) performed a 400-m fron
Measurement of respiratory muscle strength is useful in order to detect respiratory muscle weakness and to quantify its severity. In patients with severe respiratory muscle weakness, vital capacity is reduced but is a non-specific and relatively insensitive measure. Conventionally, inspiratory and expiratory muscle strength has been assessed by maximal inspiratory and expiratory mouth pressures sustained for 1 s (PImax and PEmax) during maximal static manoeuvre against a closed shutter. However, PImax and PEmax are volitional tests, and are poorly reproducible with an average coefficient of variation of 25%. The sniff manoeuvre is natural and probably easier to perform. Sniff pressure, and sniff transdiaphragmatic pressure are more reproducible and useful measure of diaphragmatic strength. Nevertheless, the sniff manoeuvre is also volition-dependent, and submaximal efforts are most likely to occur in patients who are ill or breathless. Non-volitional tests include measurements of twitch ...
The aims of this study were to determine whether caffeine administration increased respiratory muscle function and if this was associated with lung function improvement in prematurely born infants bei
Respiratory muscle function is critical for maintaining effective alveolar ventilation, and airway secretions clearance. The reduction in respiratory muscle function might lead to chronic respiratory insufficiency, and potentially to life-threatening problems. Respiratory muscle function and the impacts of various treatments regimens have not been investigated longitudinally in patients with advanced lung cancer patients.. The purposes for the 1st phase of this study are to exam longitudinal changes and the impact of various treatments on the respiratory muscle function, and the relations with dyspnea, functional capacity, quality of life, 6- and 12-month respiratory morbidity, and survival status (control group). The 2nd phase of this study will investigate the potential beneficial effects of chest physiotherapy in the same patient population (intervention group).. Methods: 102 patients with advanced lung cancer per group will be recruited from the National Taiwan University Hospital. ...
Most inspiratory muscle training (IMT) interventions in patients with chronic obstructive pulmonary disease (COPD) have been implemented as fully supervised daily training for 30 minutes with controlled training loads using mechanical threshold loading (MTL) devices. Recently, an electronic tapered flow resistive loading (TFRL) device was introduced that has a different loading profile and stores training data during IMT sessions. The aim of this study was to compare the efficacy of a brief, largely unsupervised IMT protocol conducted using either traditional MTL or TFRL on inspiratory muscle function in patients with COPD. Twenty patients with inspiratory muscle weakness who were clinically stable and participating in a pulmonary rehabilitation program were randomly allocated to perform 8 weeks of either MTL IMT or TFRL IMT. Participants performed 2 daily home-based IMT sessions of 30 breaths (3-5 minutes per session) at the highest tolerable intensity, supported by twice-weekly supervised ...
Most patients are readily liberated from mechanical ventilation (MV) support, however, 10% - 15% of patients experience failure to wean (FTW). FTW patients account for approximately 40% of all MV days and have significantly worse clinical outcomes. MV induced inspiratory muscle weakness has been implicated as a contributor to FTW and recent work has documented inspiratory muscle weakness in humans supported with MV. We conducted a single center, single-blind, randomized controlled trial to test whether inspiratory muscle strength training (IMST) would improve weaning outcome in FTW patients. Of 129 patients evaluated for participation, 69 were enrolled and studied. 35 subjects were randomly assigned to the IMST condition and 34 to the SHAM treatment. IMST was performed with a threshold inspiratory device, set at the highest pressure tolerated and progressed daily. SHAM training provided a constant, low inspiratory pressure load. Subjects completed 4 sets of 6-10 training breaths, 5 days per week.
Purpose: It has been suggested that patients with inspiratory muscle weakness could benefit from specific inspiratory muscle training (IMT). We aimed to examine the frequency of patients with inspiratory muscle weakness in a Danish hospital-based outpatient pulmonary rehabilitation program, and to evaluate the association between inspiratory muscle strength and peripheral muscle strength and walking capacity. Methods: Maximal Inspiratory Pressure (MIP) was assessed in 97 patients with COPD (39 men, 58 women, mean age years 70 ± 9, forced expiratory volume in 1 s ((FEV1) = 35 ± 10% pred.). The impact of MIP on knee-extension strength, walking distance, and symptom burden was evaluated using multiple linear regression analyses. Results: The MIP of the patients with COPD was 63 (95% CI 59; 67) cmH2O and it was significantly reduced compared to gender and age-matched reference values 76 (95% CI 73; 79) cmH2O (p , 0.001). Seven patients (7.2%) were under the lower limit of normal. MIP was ...

The aim of this study is to better discriminate respiratory muscle dysfunction by comparing the measurements of thoracoabdominal motion obtained by an optoelectronic recording and the conventional tests of respiratory muscle strength. The final objective is to better select in the future the patients who need more specific assessment of diaphragmatic function like maximal transdiaphragmatic pressure measurement and phrenic nerve stimulation ...

Materials and Methods: The correlations among BMI, changes in maximum inspiratory and expiratory pressure (ΔMIP, ΔMEP) on postoperative days (POD) 1 and 7, postoperative IL-6, and rapid turnover proteins (retinol-binding protein, prealbumin, and transferrin) on POD1 were assessed in 154 consecutive patients undergoing elective CABG. The patients were divided into quartiles of BMI, Q1 (BMI, ,20.8 kg/m2) to Q4 (BMI, ≥25.25 kg/m2), and compared among groups. Results: There were significant correlations ...

As for other skeletal muscles, ventilatory muscle performance can be described in terms of strength and endurance. Ventilatory muscle strength is measured, for example, as the maximum inspiratory and expiratory mouth pressures. It is now a routine procedure in many pulmonary function laboratories. Measurements of ventilatory muscle endurance are more difficult but two general types of tests are used: maximum voluntary ventilation and inspiratory threshold loading. [less ▲].

Respiratory muscle strength can be assessed by measuring the maximal inspiratory pressure (MIP or PImax), and the maximal expiratory pressure (MEP or PEmax). The MIP reflects the strength of the diaphragm and other inspiratory muscles, while the MEP
The majority of my work has been directed at evaluating respiratory muscle function in health and disease. My initial research in this area focused on evaluating determinants of respiratory muscle endurance in healthy individuals. Among my significant contributions in this area were the findings that mean inspiratory flow rate, operational lung volume, and muscle energetics were key determinants of inspiratory muscle endurance. By extending these observations to patients with tetraplegia, Parkinsons Disease, diaphragm paralysis, and flail chest, we obtained a better understanding of respiratory muscle dysfunction in patients with varied diseases of the chest wall. While completing the above studies, it became apparent that the tools available to assess respiratory muscle function were limited due to their invasive nature. Consequently I became interested in developing ultrasound as a non-invasive tool to assess diaphragm function. After determining that diaphragm thickness could be accurately ...

The functional outcomes of respiratory muscle loading by chemical (e.g. hypercapnia), mechanical (i.e. external mechanical loading) or ventilatory (e.g. exercise) factors can be either positive, such as through an increase in pressure-generating capacity of the inspiratory muscles or detrimental, such as by fatigue. Neurophysiological responses to respiratory muscle loading can occur at one or more points along the pathway from motor cortex to muscle. This paper describes the respiratory pump and upper airway motoneuron responses to the imposition of acute loads including processes of pre-activation, respiratory reflexes, potentiation and fatigue. It also considers changes suggestive of adaptation to chronic loading either from specific respiratory muscle training programs or as part of disease processes such as chronic obstructive pulmonary disease or obstructive sleep apnoea.. ...
The underlying pathophysiological mechanisms responsible for the impairment in respiratory muscle strength in patients with PH have not yet been investigated conclusively. On the basis of observations mainly derived from chronic left heart failure, several mechanisms accounting for a reduction in respiratory muscle strength have been suggested. Structural skeletal muscle abnormalities and abnormal expression of myosin isoforms, highly suggestive of fibre type transformation predominantly pronounced in the diaphragm of patients with chronic left heart failure, have been reported [29]. Furthermore, fibre type changes associated with a myopathic pattern [30], cross-sectional muscle fibre reduction [31] and fast-to-slow transformations of myosin and regulatory proteins [32,33] in the diaphragm have also been reported. In addition, besides an intracellular calcium regulation disorder in the diaphragms of patients with chronic left heart failure [34], the occurrence of a depressed oxidative capacity ...
Polymyositis is a rare medical disorder complicating pregnancy. Ventilatory muscle weakness leading to respiratory failure is an uncommon manifestation of this autoimmune disease. We report a case of life-threatening hypercapnic respiratory failure due to polymyositis-related respiratory muscle weakness in a pregnant woman. A 31-year-old, African woman in her second trimester of pregnancy presented to the emergency department with fever, shortness of breath and muscle weakness. Initial investigations excluded pulmonary infection, thromboembolism, and cardiac dysfunction as the underlying cause of her symptoms. She developed deterioration in her level of consciousness due to carbon dioxide narcosis requiring invasive mechanical ventilation. Further workup revealed markedly elevated serum creatine kinase, abnormal electromyography and edema of her thigh muscles on magnetic resonance imaging. Diagnosis of polymyositis was confirmed by muscle biopsy. After receiving pulse steroid, intravenous

Backgrounds: Respiratory muscle strength is recognized to be impaired in patients with COPD, while its severity in Chinese COPD patients and the related factors remains unclear. Twitch mouth pressure (TwPM) responded to cervical magnetic stimulation is a non-volitional technique to measure respiratory muscle strength. Thus, the present study was aimed to quantify the severity of respiratory muscle weakness at different stages of COPD, and to investigate the potential factors related to TwPM in COPD.. Methods: Seventy-five patients with COPD and sixty-three age-matched controls participated in the study. Pulmonary function was tested for each participant. Respiratory muscle strength was assessed with measurement of both TwPM and non-volitional static mouth pressures. A score of physical activity (PA score) was obtained using an adapted physical activity questionnaire for the elderly, and nutritional status was evaluated with a multiple-nutritional index. Multiple regression models were developed ...
Methods. Ninteen well-trained rowers were divided into two groups: IMT (T) and control (C). The T group, in addition to their daily rowing practice, performed IMT by means of a threshold inspiratory muscle trainer for ~0.5h·d-1, 5 times a week for 6 weeks. The C group participated only in their regular daily rowing training. Prior to the initiation and at the completion of the 6-week IMT program, both groups underwent an incremental treadmill run test to determine V.O2max. Maximum inspiratory mouth pressure (PImax) was measured at rest and following the V.O2max test. On a separate occasion, rowing performance was evaluated by a 2 000 m all-out effort on a rowing ergometer. Dyspnea sensation was assessed by a modified Borg scale and Lmax was measured by an enzymatic method ...
The present study therefore aims to investigate the pathophysiology of respiratory muscle dysfunction in patients with optimally treated, stable HFrEF by means of multi-modal respiratory and skeletal muscle strength testing (including diaphragm ultrasound, magnetic phrenic nerve Stimulation with assessment of transdiaphragmatic pressures and transdiaphragmatic pressures after a comprehensive set of voluntary tests). That said answers can be given (1) to the question whether respiratory muscle dysfunction contributes to the sensation of breathlesness and/or exercise intolerance independent from left ventricular function in HF. (2) to the question what the natural time course of respiratory muscle dysfunction in these patients looks like ...
Electrical muscle stimulation (EMS) can prevent critical illness polyneuromyopathy (CIPNM), according to Greek researchers. CIPNM is an acquired limb and respiratory muscle weakness that is a common and serious problem among intensive care unit patients, and can result in prolonged ICU and hospital stay. EMS can also shorten the duration of weaning from mechanical ventilation and the length of ICU stay.. The study was presented at the ATS 2010 International Conference in New Orleans.. CIPNM is a very common complication of critical illness and ICU stay affecting approximately one-quarter of ICU patients and is characterized by profound muscle weakness or even paralysis. No preventive tool has been reported so far for critical illness polyneuromyopathy, said Serafim Nanas, M.D., associate professor at the National and Kapodistiran University of Athens, First Critical Care Medicine Department, and the principal investigator of the study. ICU patients undergo long periods of immobilization due ...

Pulmonary hyperinflation is commonly divided into static and dynamic in patients with chronic obstructive pulmonary disease (COPD). The former can be directly attributed to the emphysema-related reduction in lung elasticity, leading to a larger volume at which lung and chest wall recoil pressures are balanced. As a consequence, both total lung capacity and functional residual capacity increase above their normal levels. Conversely, dynamic hyperinflation (DH) is caused by expiratory airflow limitation, air trapping and auto-positive end-expiratory pressure. This further increases functional residual capacity.. Extensive literature has accumulated on the objective and subjective manifestations and sequelae of pulmonary hyperinflation in COPD, including effects on respiratory muscle function, ventilation, work of breathing, exercise tolerance, cardiovascular function, dyspnoea and health status. The purpose of the articles in this issue of the European Respiratory Review is to summarise some of ...
Assessment of maximum respiratory pressures is a common practice in intensive care because it can predict the success of weaning from ventilation. However, the reliability of measurements through an intubation catheter has not been compared with standard measurements. The aim of this study was to compare maximum respiratory pressures measured through an intubation catheter with the same measurements using a standard mouthpiece in extubated patients. A prospective observational study was carried out in adults who had been under ventilation for at least 24 h and for whom extubation was planned. Maximal respiratory pressure measurements were carried out before and 24 h following extubation. Ninety patients were included in the analyses (median age: 61.5 years, median SAPS2 score: 42.5 and median duration of ventilation: 7 days). Maximum respiratory pressures measured through the intubation catheter were as reliable as measurements through a standard mouthpiece (difference in maximal inspiratory pressure:
Comparison of Pimax and Pemax before and after CPET in the same individuals in relation to oxygen kinetics has not been previously examined. Therefore, in this study, Pimax and Pemax measurements were repeated at 10 minutes into recovery from exercise. In agreement with previous findings, a weak (although statistically significant) correlation, before and after CPET, existed between Pimax and peak V̇o2.17 34 Assuming that the fall in V̇o2 during early recovery from exercise is linear, V̇o2 recovery in patients with CHF was examined in a linear regression model. Our measurements applied to the fast component (alactic phase) of the repayment of the oxygen debt.30 Investigators who studied the repayment of oxygen debt have used single23 35 36 and double exponential equations36 to describe the fall in V̇o2 during the recovery period. It was observed in stable workload protocols that the time constant and half-time (T1/2) derived from it were independent of the work level.35 Recently, Cohen-Solal ...
1. The physiological basis of inspiratory effort sensation remains uncertain. Previous studies have suggested that pleural pressure, rather than inspiratory muscle fatigue, is the principal determinant of inspiratory effort sensation. However, only a limited range of inspiratory flows and breathing patterns have been examined. We suspected that inspiratory effort sensation was related to the inspiratory muscle tension-time index developed whatever the breathing pattern or load, and that this might explain the additional rise in sensation seen with hypercapnia.. 2. To investigate this we measured hypercapnic re-breathing responses in seven normal subjects (six males, age range 21-38 years) with and without an inspiratory resistive load of 10 cm H2O. Pleural and transdiaphragmatic pressures, mouth occlusion pressure and breathing pattern were measured. Diaphragmatic and ribcage tension-time indices were calculated from these data. Inspiratory effort sensation was recorded using a Borg scale at 30s ...
Surface electromyography (sEMG) can be used for the evaluation of respiratory muscle activity. Recording sEMG involves the use of surface electrodes in a bipolar configuration. However, electrocardiographic (ECG) interference and electrode orientation represent considerable drawbacks to bipolar acquisition. As an alternative, concentric ring electrodes (CREs) can be used for sEMG acquisition and offer great potential for the evaluation of respiratory muscle activity due to their enhanced spatial resolution and simple placement protocol, which does not depend on muscle fiber orientation. The aim of this work was to analyze the performance of CREs during respiratory sEMG acquisitions. Respiratory muscle sEMG was applied to the diaphragm and sternocleidomastoid muscles using a bipolar and a CRE configuration. Thirty-two subjects underwent four inspiratory load spontaneous breathing tests which was repeated after interchanging the electrode positions. We calculated parameters such as (1) spectral ...
Obstructive sleep apnoea is a sleep disorder that affects more than 4% of the population and can lead to symptoms from daytime drowsiness to high blood pressure. People with sleep apnoea are often not breathing normally during sleep and may experience periods where the airway closes and they are unable to breathe. In severe sleep apnoea this can occur 50-60 times each hour. That is once each minute. The closure of the upper airway is thought to be due to a number of factors, one of which is that the neural drive to the airway muscles is insufficient in people with sleep apnoea. In our lab, we have made the first extensive recordings from the major muscle of the upper airway, genioglossus. We have shown that the neural drive to this muscle is very complex, more so than any limb muscle. At NeuRA, we have also pioneered new methods to image this muscle using fMRI and ultrasound. We are now planning to look at how changes in muscle architecture and mechanics relate to the neural drive to the muscle ...
Scientific Basis. Decramer and Macklem introduced a method for inferring respiratory muscle action by measuring esophageal and gastric pressures (23) For example, inhalations made with rib cage muscles alone (as in diaphragm paralysis) result in decreases in both esophageal pressure, which is normal, and in gastric pressure, which is not, whereas diaphragmatic inhalations result in increased gastric pressure and a negative swing in Pes (lung inflation) (Figure 5).. Advantages. This technique is useful and informative when esophageal and abdominal pressures are recorded.. ...

After cervical spinal cord injury (SCI), the respiratory muscles are partly or completely paralysed. This has two major clinical consequences: a decreased ability to get air into the lungs and a decreased ability to cough and remove secretions. This results in a lifetime of recurrent respiratory tract infections (2/year/person) that often progress to pneumonia with frequent and extended hospital admissions. People with cervical SCI are 150 times more likely to die from respiratory complications than the general population, as many as 28% die within the first year after injury. For those that survive the first year, a cervical SCI has a lifetime cost of $9.5million, a large proportion of which is attributed to respiratory-related complications. A recent longitudinal study of people with cervical SCI showed that respiratory muscle weakness is associated with incidental pneumonia. Respiratory muscle weakness also causes dyspnoea (breathlessness) and sleep-disordered breathing, which is 4-10 times ...
During intensive exercise, the breathing muscles have a significant rising oxygen demand in line with the increase of speed and volume of breathing (hyperpnoea)1. These respiratory muscles are at risk of fatigue, especially during endurance sports. As the breathing rate and volume increase during near maximal exercise, blood flow to the legs is significantly altered1.. The bodys sensitivity to blood carbon dioxide also has an impact on the work of the respiratory muscles during exercise. If your BOLT score is low, you will breathe harder when exercise intensifies. Breathing hard requires a lot of work from the respiratory muscles, and as these muscles become fatigued, blood is diverted from the legs to support breathing9. This redistribution of blood away from the working muscles is called metaboreflex. It makes your legs feel tired, forcing you to slow down or stop. When the respiratory muscles overwork, metabolic by-products like lactic acid collect in the tissues, causing reduced circulation ...
The reduced TLC showed a mild restrictive defect. At the same time the relatively normal DLCO indicates that the restriction is probably not due to interstitial lung disease and more likely either a chest wall or a neuromuscular disorder, both of which can prevent the thorax from expanding completely but where the lung tissue remains normal. The reduced MIP and MEP tends to suggest that a neuromuscular disorder is the more likely of the two. I take this with a grain of salt however, and that is because this individual never had pulmonary function tests before and for this reason there is no way to know what their baseline DLCO was prior to the restriction. At the same time far too many individuals perform the MIP/MEP test poorly and low results are not definitive, and in this case in particular the results are so low the individual should have been in the ER, not the PFT Lab.. The CPET results were somewhat complicated, in that a close inspection showed both pulmonary and cardiovascular ...

Calling For Breath during your massage is one of the most important elements of getting a massage. Were told from a young age to hold in our gut to help our posture and waistline appearance. Unfortunately, all this does is force us to breathe higher up into our necks and upper chest and places unnecessary strain on secondary respiratory muscles that support our neck and ribcage.. Belly breathing allows us to make use of the primary respiratory muscle, the diaphragm, to bring air into our lungs and tap into vital lung capacity. More oxygen enters our blood stream and secondary respiratory muscles such as the scalenes, sternocleidomastoid (SCM), and intercostals remain within capacity without strain. Bringing our breath down into our bellies helps with digestion; allowing movement within our abdominal cavity massages digestive and other abdominal organs, pumping fresh blood in and waste products out of the tissues. Abdominal breathing or breath work is taught in yoga, voice classes, and ...

Like all other muscles, we can improve our respiratory muscles with stretching and strength training exercises. We even can increase our vital lung capacity, allowing us to inhale more air and thus increase our oxygen intake with each breath.. Being able to inhale more oxygen for each breath brings many benefits. Youll feel more energized, recover faster from injuries and trauma and perform at peak performance. More and more top athletes and other high performance professionals are taking up breath training as at the highest level of competition, more oxygen gives a serious advantage.. Training the respiratory muscles is also invaluable for people that suffer from a condition that reduces your breathing ability, such as COPD, asthma or pneumonia. When your ability to breathe is compromised, your body will not get the amount of oxygen it needs to be fully energized. Strengthening your respiratory muscles and making them more flexible can help minimize the negative impact of illnesses and ...
During rounds with the gung ho doctor, he was very ready to start weaning and pull the tube. I expressed concerns about her not being ready to wean vent settings in preparation of pulling the breathing tube because she was still symptomatic of rhinovirus (which is what got her intubated in the first place) and acting sick. She already works hard to breathe and just couldnt handle the work of being sick on top of the work she was already doing. Respiratory muscle fatigue kept her from ventilating like she should. Also, I expressed concern about the method they were wanting to use to wean her vent settings. They were wanting to wean her peep (the tiny air pockets in the lungs staying at least mildly inflated even when inhaling) relatively quickly and put her in volume support instead of pressure support. Aubree has always pulled pretty great volumes, but struggles with peep because of her chest being restricted. Also, from her previous extubation after surgery, she did not tolerate volume ...

The next discussion was with Dr Peter Cho where we discussed some of the physical effects on the body such as breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages. The most intriguing fact we learned in that discussion, in my opinion was the fact that there is permanent damage to the air sacs of the lungs due to scarring from the constant strain from coughing. In the discussion with Dr Alexis Cullen we were stimulated to think about possible relationships between mental health and smoking. For instance, ways in which we could test whether individuals with mental health are more likely to smoke or whether smoking led to and/or worsened mental health. What I found most fascinating was the fact that research needs to be cautious of third factors that could affect the investigation. For example, a third factor could be the socio-economic background of the individuals causing them to either start smoking or affecting their mental health. The final ...

Radiological data showed left-sided pleuritis, minimal pleural effusion. Pleural effusion resolved spontaneously in one week later but patient had still dyspnea. Pulmonary function tests (PFT) was normal. Further examination detected respiratory muscle weakness and decreased functional capacity. Patient then underwent inspiratory muscle training (IMT) for six weeks. After training, inspiratory muscle strength and functional capacity increased. Perception of dyspnea and fatique decreased. In long-term follow-up, frequency of attacks decreased. To our knowledge, there is no study on respiratory muscle weakness ...
BACKGROUND AND PURPOSE: Cough protects the lungs from aspiration. We investigated whether respiratory muscle training may improve respiratory muscle and cough function, and potentially reduce pneumonia risk in acute stroke. METHODS: We conducted a single-blind randomized placebo-controlled trial in 82 patients with stroke (mean age, 64±14 years; 49 men) within 2 weeks of stroke onset. Participants were masked to treatment allocation and randomized to 4 weeks of daily expiratory (n=27), inspiratory (n=26), or sham training (n=25), using threshold resistance devices. Primary outcome was the change in peak expiratory cough flow of maximal voluntary cough. Intention-to-treat analyses were conducted using ANCOVA, adjusting for baseline prognostic covariates. RESULTS: There were significant improvements in the mean maximal inspiratory (14 cmH2O; P,0.0001) and expiratory (15 cmH2O; P,0.0001) mouth pressure and peak expiratory cough flow of voluntary cough (74 L/min; P=0.0002) between baseline and 28 ...

Methods: A prospective, randomized, controlled design was used. Twenty-nine patients with chronic respiratory failure were enrolled and allocated to either the NNPPV (n = 14) or control group (n = 15). Patients in the NNPPV group received bi-level positive pressure ventilation via nasal mask for 6 consecutive months. Arterial blood gas, respiratory muscle assessment and 6-minute walk test (6MWT) were performed before and ...
The current body of clinical research work confirms the complex mechanisms that are in place between the respiratory system and the circulatory systems of the human body. This paper attempts to capture that information in a form that addresses the scope of the work and how it applies to the respiratory muscle training uniquely provided by PowerLung products.Twelve (12) sets of muscles are used in breathing. These muscle groups are used for both inhale and exhale. Principles of strength training in the literature show improved co-ordination and efficiency results by training both agonist and antagonist muscle groups. (Sale 1988) Like other sets of muscles, the respiratory muscles can be trained for improvement in strength, endurance or both. (Pardy, et al 1988 ...
We assessed the effects of respiratory muscle training (RMT) in patients with multiple sclerosis (MS) on vital capacity (VC), maximal static inspiratory (PImax) and expiratory (PEmax) pressures and maximal voluntary ventilation (MVV). Eight patients
BACKGROUND: After stroke, pneumonia is a relevant medical complication that can be precipitated by aspiration of saliva, liquids, or solid food. Swallowing difficulty and aspiration occur in a significant proportion of stroke survivors. Cough, an important mechanism protecting the lungs from inhaled materials, can be impaired in stroke survivors, and the likely cause for this impairment is central weakness of the respiratory musculature. Thus, respiratory muscle training in acute stroke may be useful in the recovery of respiratory muscle and cough function, and may thereby reduce the risk of pneumonia. The present study is a pilot study, aimed at investigating the validity and feasibility of this approach by exploring effect size, safety, and patient acceptability of the intervention. METHODS/DESIGN: Adults with moderate to severe stroke impairment (National Institutes of Health Stroke Scale (NIHSS) score 5 to 25 at the time of admission) are recruited within 2 weeks of stroke onset. ...

Study Start Date: March 2017 Study Type: Interventional Condition: Swallowing Disorder Stroke Respiratory Muscle Training Malnutrition Intervention: Device: High intensity IEMT Training load will be the maximum inspiratory / expiratory load defined according to patient tolerance equivalent to 10 maximal repetitions (RM) as 10 consecutive inspirations / expirations (x 5 set), twice a day, ...
Hypertension is a complex chronic condition characterized by elevated arterial blood pressure. Management of hypertension includes non-pharmacologic strategies, which may include techniques that effectively reduce autonomic sympathetic activity. Respiratory exercises improve autonomic control over cardiovascular system and attenuate muscle metaboreflex. Because of these effects, respiratory exercises may be useful to lower blood pressure in subjects with hypertension. This randomized, double-blind clinical trial will test the efficacy of inspiratory muscle training in reducing blood pressure in adults with essential hypertension. Subjects are randomly allocated to intervention or control groups. Intervention consists of inspiratory muscle training loaded with 40 % of maximum inspiratory pressure, readjusted weekly. Control sham intervention consists of unloaded exercises. Systolic and diastolic blood pressures are co-primary endpoint measures assessed with 24 h ambulatory blood pressure ...

An increased work of breathing during heavy whole body exercise can lead to respiratory muscle fatigue (RMF) and decreased leg blood flow. Heavy exercise also increases inactive limb and cutaneous blood flow. It is not known, however, how RMF affects inactive limb and cutaneous blood flow. Therefore, we tested the hypothesis that RMF during heavy exercise would reduce: 1) inactive limb blood flow, 2) inactive limb vascular conductance, and 3) inactive limb cutaneous blood flow. Twelve healthy men (23 ± 2 yrs) completed baseline pulmonary function tests followed by an incremental cycle test to VO[subscript]2[subscript]max. Subjects then cycled at both 70% and 85%VO2max (randomized) for 20 minutes. Subjects performed a second 85%VO[subscript]2[subscript]max test ingesting N-acetylcysteine (NAC) (1800mg), which has been reported to reduce RMF, 45 minutes prior the test. Maximum inspiratory pressures (P[subscript]Imax) were measured prior to and immediately following each exercise trial to ...
It is unknown whether the respiratory muscles contribute to exercise-induced increases in plasma interleukin-6 (IL-6) concentration, if this is related to diaphragm fatigue, and whether inspiratory muscle training (IMT) attenuates the plasma IL-6 response to whole body exercise and/or a volitional mimic of the exercise hyperpnea. Twelve healthy males were divided equally into an IMT or placebo (PLA) group, and before and after a 6-wk intervention they undertook, on separate days, 1 h of 1) passive rest, 2) cycling exercise at estimated maximal lactate steady state power (EX), and 3) volitional hyperpnea at rest, which mimicked the breathing and respiratory muscle recruitment patterns achieved during EX (HYPEX). Plasma IL-6 concentration remained unchanged during passive rest. The plasma IL-6 response to EX was reduced following IMT (main effect of intervention, P = 0.039) but not PLA (P = 0.272). Plasma IL-6 concentration increased during HYPEX (main effect of time, P , 0.01) and was unchanged ...
The plasma concentration of interleukin-6 (IL-6) increases during cycling exercise (EX) (Starkie et al. J. Physiol 2001; 533:585-591) and inspiratory resistive breathing (IRB) (Vassilakopoulos et al. Am. J. Physiol 1999; 277:R1013-R1019). Whether inspiratory muscle training (IMT) can attenuate the magnitude of the IL-6 response to EX and volitional hyperpnoea (VH) rather than IRB is unknown. Therefore, we tested the hypothesis that IMT would reduce the IL-6 response to EX and/or VH.. Twelve male participants performed either 6 weeks of pressure-threshold IMT (n=6) or placebo (PLA) training (n=6). Before and after training, participants undertook three 1 hour experimental trials on separate days: (i) passive rest; (ii) EX; and (iii) VH. EX was performed at maximum lactate steady state power. In VH, participants voluntarily mimicked at rest the breathing and respiratory muscle recruitment pattern attained during EX.. IL-6 peaked immediately after EX for both the IMT and PLA groups (6.75 ± 1.6 and ...
Discussion. RMS was improved to a level superior to that witnessed in 50-59 yr females from the same demographic (Watsford et al., 2002), to a level of 30-39 yr females (Neder et al., 1999). An increase in RMS may improve exertional respiratory efficiency, thus impacting on submaximal walking performance. In turn, there may be decreased respiratory muscle blood flow during exercise, accounting for the improvement in oxygen consumption. Improved walking efficiency will have large implications for exercise participation and adherence in this age group, as many tasks undertaken by this age group are within this intensity range. These individuals may have the capacity to perform a greater quantity of exercise following RMT intervention and therefore have the capacity to maintain or improve health to a greater degree. Mobility impairments cause many older individuals to be restricted from performing exercise of moderate to high intensity. When attempting to improve fitness level, elevated intensity ...
This study investigated the effects of inhaled vilanterol/fluticasone furoate on breathing pattern, dyspnoea and respiratory muscle function in patients with
It has been suggested that NIV works by resting chronically fatigued respiratory muscles.53 However, research in this area has been hampered by the absence of good tests of respiratory muscle fatigue and conflicting results have been reported. Small increases in mouth pressure have been cited as evidence of improved capacity though, in the absence of a control group, these may have been due to learning effects and better motivation; other studies54-57 have reported improved daytime arterial blood gas tensions in the absence of changes in the indices of respiratory muscle strength. Shapiro et al 58 studied 184 patients with COPD randomised to receive active or sham negative pressure ventilation at home using a poncho wrap ventilator. They did not show any significant difference between the two groups but compliance with treatment was much less than anticipated. They compared their primary end point, a six minute walking test, with the dose of respiratory muscle rest actually delivered and ...

Alterations to the supply of oxygen during early life presents a profound stressor to physiological systems with aberrant remodeling that is often long-lasting. Chronic intermittent hypoxia (CIH) is a feature of apnea of prematurity, chronic lung disease and sleep apnea. CIH affects respiratory control but there is a dearth of information concerning the effects of CIH on respiratory muscles, including the diaphragm - the major pump muscle of breathing. We investigated the effects of exposure to gestational CIH (gCIH) and postnatal CIH (pCIH) on diaphragm muscle function in male and female rats. CIH consisted of exposure in environmental chambers to 90s of hypoxia reaching 5% O2 at nadir, once every 5 min, 8 hrs a day. Exposure to gCIH started within 24 hours of identification of a copulation plug and continued until day 20 of gestation; animals were studied on postnatal day 22 or 42. For pCIH, pups were born in normoxia and within 24h of delivery were exposed with dams to CIH for 3 weeks; animals were
Maximal functional capacity was evaluated with an incremental exercise test, with expired gas analysis, on a treadmill (INBRAMED 10200, Porto Alegre, Brazil), using a ramp protocol, starting at a speed of 2.4 km·h−1and 2% slope, with 20-s increments of speed (0.1 to 0.2 km·h−1) and 60-s increments in slope (0.5% to 1.0%), to reach volitional fatigue at approximately 10 min. Twelve-lead electrocardiographic tracings were obtained every minute (Nihon Khoden Corp., Tokyo, Japan). Blood pressure was measured every 2 min with a standard cuff sphygmomanometer. Metabolic and ventilatory variables were measured during and after exercise by 20-s mean aliquots, by a computer-aided gas analyzer (Total Metabolic Analysis System, TEEM 100, Aero Sport, Ann Arbor, Michigan), previously validated (17). Peak oxygen uptake (V̇o2peak) was considered the highest value of V̇o2calculated in a period of 20 s of exercise. Maximal circulatory power was calculated as the product of V̇o2peak and peak systolic ...
To our knowledge, no data have been provided as to whether and to what extent dynamic hyperinflation, through its deleterious effect on inspiratory muscle function, affects the perception of dyspnoea during induced bronchoconstriction in patients with chronic airflow obstruction. We hypothesized that dynamic hyperinflation accounts in part for the variability in dyspnoea during acute bronchoconstriction. We therefore studied 39 consecutive clinically stable patients whose pulmonary function data were as follows (% of predicted value): vital capacity (VC), 97.8% (S.D. 16.0%); functional residual capacity, 105.0% (18.8%); actual forced expiratory volume in 1s (FEV1)/VC ratio, 56.1% (6.3%). Perception of dyspnoea using the Borg scale was assessed during a methacholine-induced fall in FEV1. The clinical score and the treatment score, the level of bronchial hyper-responsiveness and the cytological sputum differential count were also assessed. In each patient, the percentage fall in FEV1 and the ...
BACKGROUND--Inspiratory muscle strength is often better reflected by oesophageal pressure during a maximal sniff (sniff POES) than by maximal inspiratory pressure (PImax). Sniff POES can be estimated non-invasively by measuring the sniff nasal inspiratory pressure (SNIP). The aim was to establish maximal normal values for the SNIP and to compare them with PImax. METHODS--One hundred and sixty healthy subjects (80 men) aged 20-80 years were recruited. All subjects had a forced vital capacity (FVC) of , 80%, a forced expiratory volume in one second (FEV1)/FVC of , 85% predicted value, and a body mass index of 18-31 kg/m2. Because PImax is known to be reduced in the supine posture, the SNIP was measured in both the sitting and the supine positions. PImax sustained over one second was measured from functional residual capacity (FRC) in the sitting position with a standard flanged mouthpiece during four manoeuvres. SNIP was measured from FRC in the sitting and supine positions using a catheter ...
The group collaborated with the Hospital del Mar-IMIM in Barcelona to tackle the current lack of instruments for assessing respiratory muscle activation during the breathing cycle in clinical conditions.. Read more…. Working together with the hospitals Department of Respiratory Medicine, IBECs Biomedical Signal Processing and Interpretation group tested respiratory muscle mechanomyography (MMG) as a way to assess the mechanical activation of the inspiratory muscles of the lower chest wall in both patients with chronic obstructive pulmonary disease (COPD) and healthy subjects. This non-invasive method confirmed the relationship between inspiratory muscle activation characterised by a non-linear index (MLZ: multistate Lempel-Ziv) and pulmonary function parameters.. Their results suggest that respiratory muscle MMG is a good reflection of inspiratory effort, and could be used in clinical conditions to estimate the efficiency of the mechanical activation of the inspiratory muscles, contributing ...
Our results show that VIS and FIS increased pulmonary volumes in healthy adults; however, VIS induced a greater total chest wall volume, especially in the abdominal compartment, and lower respiratory muscle activity, compared to FIS. Moreover, we observed that only FIS promoted thoracoabdominal asynchrony. To the best of our knowledge, this is the first study to compare both types of incentive spirometry using accurate equipment that allows chest wall volume assessment in a 3-dimensional and 3-compartment analysis that also simultaneously quantifies the respiratory muscle activity.. Although VIS or FIS are widely used and recommended in clinical practice, especially for perioperative care, there is no consensus about their benefits or indications, and no study has demonstrated which incentive spirometer is the most effective.22-24 This is most likely because few studies have assessed the differences in respiratory mechanics between the 2 devices. Parreira et al10 and Tomich et al11 evaluated ...

After major abdominal or heart surgery, people can experience a number of complications. These include lung infections (pneumonia), areas of collapsed lung from plugs of secretions in the airways, constricted airways or fluid in or around the lung.. These may lead to respiratory failure (where the lungs cannot get enough oxygen into the blood stream). Such complications are associated with higher healthcare costs, longer stays in hospital, on-going illness and death.. Prior to surgery people identified at risk can perform exercises supervised by a physiotherapist - called respiratory rehabilitation - designed to reduce the risk of complications. Inspiratory muscle training, which helps to strengthen the muscles around the lungs, is one example of a respiratory rehabilitation technique.. This Cochrane review evaluated the effectiveness of inspiratory muscle training in people undergoing heart or major abdominal surgery, compared with usual care (such as advice on deep breathing exercises), a ...

Definition of inspiratory pressure in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is inspiratory pressure? Meaning of inspiratory pressure as a legal term. What does inspiratory pressure mean in law?
It should be emphasized that CPAP levels should be carefully titrated to the individual patients subjective response; levels in excess of the inspiratory threshold load will result in further hyperinflation and attendant potentially deleterious mechanical, hemodynamic, and sensory consequences. Theoretically, CPAP could be used as an adjunct to exercise training. By prolonging exercise duration, CPAP may permit some very breathless patients to reach the hitherto unattainable threshold at which physiologic training effects are achieved. The potential utility of CPAP in the rehabilitative setting warrants further investigation.. In summary, while the most obvious mechanical defect in CAL is increased expiratory resistance, the major mechanical consequence is inspiratory muscle loading. Qualitatively, breathlessness in CAL primarily encompasses the perception of inspiratory difficulty and is commonly expressed in terms of heightened inspiratory effort or awareness of unrewarded inspiratory effort ...

  • In patients with severe diaphragmatic involvement both symptoms of SDB and potential complications of respiratory muscle weakness substantially add to overall disease burden of the disease and decrease life span. (
  • For this reason it is desirable to thoroughly screen patients with neuromuscular disease for symptoms of SDB and respiratory muscle weakness. (
  • Until now, there is no validated German language screening questionnaire for symptoms of respiratory muscle weakness and SDB. (
  • A muscle disorder includes patterns of weakness, loss of muscle tissue, electromyogram (EMG) findings, or biopsy results that suggest a muscle problem. (
  • The characteristic muscle weakness occurs because of a progressive degeneration of the alpha motor neuron from anterior horn cells in the spinal cord. (
  • without it, those nerve cells cannot properly function and eventually die, leading to debilitating and often fatal muscle weakness. (
  • Join leading experts, Sigfredo Aldarondo, MD, and Nina Bausek, PhD. They'll discuss how improving respiratory muscle weakness can help reduce hospital readmissions and improve patient quality of life. (
  • Patients with Parkinson's Disease (PD) often develop respiratory weakness and lower lung capacities. (
  • Respiratory weakness can also lead to one of the most common causes of death in people with Parkinson's Disease -aspiration pneumonia-especially in the late stages of the disease. (
  • Weakness of your breathing muscles. (
  • Earlier studies have suggested that weakness of the breathing muscles are linked to a poor prognosis, but up to now, no one had directly compared different types of measures. (
  • It is not surprising that this choreography is profoundly disturbed by muscle weakness in neuromuscular conditions and by dystonia and poor coordination in cerebral palsy. (
  • WXIN) - Doctors across the United States have seen an increase in children of a respiratory virus that can cause polio-like muscle weakness. (
  • Those who suffer from AFM may find it difficult to move their arms while others experience muscle weakness. (
  • symptoms such as myalgia, muscle weakness and transitory edema may occur. (
  • Consequently, more data "will be needed in the future to validate these initial findings" and to determine in which COVID-19 patients respiratory muscle weakness is the "most prevalent" feature. (
  • Symptoms include sudden arm or leg weakness and loss of muscle tone and reflexes. (
  • In contrast, in muscle-specific InsR knockout (MIRKO) and streptozotocin (STZ)-treated hypoinsulinemic, hyperglycemic mice, levels of mitochondrial respiratory chain complexes and mitochondrial function were markedly reduced. (
  • In addition, weighted gene co-expression network analysis within both breeds identified several co-expression modules that were associated with the proportion of different fiber types, mitochondrial respiratory activity, and ATP metabolism. (
  • In contrast to PiNN, co-expression modules enriched in macromolecule catabolic process, actin cytoskeleton, and transcription activator activity were associated with fiber types, mitochondrial respiratory activity, and metabolic enzyme activities. (

  • Respiratory alkalosis may resemble the symptoms pneumonia , acute respiratory distress syndrome, and sepsis , among others. (
  • And antioxidants produced during endurance exercise may prevent or reduce the severity of acute respiratory distress syndrome (ARDS), which has been "a serious and common outcome among those hospitalized with COVID-19. (
  • Respiratory therapy devices are used to mobilize secretions and help loosen and eleminate mucus. (
  • Contact with respiratory secretions. (
  • 6 Even between feeds, there is likely to be recurrent aspiration of non-sterile oral and upper respiratory secretions into the (normally sterile) lower airways because of inadequate protective reflexes. (
  • Increased secretions muscle tremors. (
  • It can also be transmitted through respiratory secretions during prolonged face-to-face contact, sex, kissing, snuggling, or even by respiratory secretions during talks. (
  • The results indicate that the timing of muscle contraction can affect the heart rate variability even at the frequency band of respiration. (
  • Here, gene expression was investigated in malignant hyperthermia syndrome (MHS)-negative Duroc and Pietrian (PiNN) pigs significantly differing for the muscle fiber types slow-twitch-oxidative fiber (STO) and fast-twitch-oxidative fiber (FTO) as well as mitochondrial activity (succinate-dependent state 3 respiration rate). (
  • The rate of respiration can be one of the most apparent symptoms of respiratory alkalosis. (
  • The use of a CPAP machine won't prevent you from getting regular respiratory infections, so there's also a chance you may develop symptoms of an unrelated respiratory infection. (
  • You may need treatment for a variety of respiratory infections, including COVID-19 , influenza , pneumonia , or strep throat . (
  • Although regular CPAP machine use does not link to increased respiratory infections, there have been cases of infections due to contaminated or improperly maintained CPAP devices. (
  • Unlike many other viral respiratory infections, such as the common cold, the flu causes severe illness and life-threatening complications in many people. (
  • Muscles produce compounds during physical activity that strengthen two biological processes (immune system function and inflammation reduction), which can potentially reduce the severity of COVID-19 infections in the lungs. (
  • Respiratory muscle training is considered an effective pre-operative measure for people suffering from pulmonary complications. (
  • Before we move to discuss the Respiratory Muscle Training (RMT) for COVID-19 patients and how the virus affects the pulmonary system, it is essential to discuss what RMT is. (
  • A specially trained respiratory therapist usually performs pulmonary function testing. (
  • Some people, such as those with chronic obstructive pulmonary disease, may experience chronic respiratory alkalosis due to continuing hyperventilation. (
  • Upper-extremity, lower-extremity and trunk isometric muscle strength and pulmonary function tests measurements were performed to the athletes on two different days. (
  • A retrospective study was made in Riyadh, Saudi Arabia, on the impact of pulmonary rehabilitation on respiratory parameters and health care utilization in a group of outpatients with chronic lung diseases other than chronic obstructive pulmonary disease. (
  • Adam MacNeil] Hantavirus pulmonary syndrome, or HPS, is a severe respiratory infection caused by certain types of viruses known as hantaviruses. (
  • Initial symptoms of HPS resemble many common illnesses and include fever, muscle aches, headache, and possibly vomiting. (
  • Legionnaires' disease is very similar to other types of pneumonia, with symptoms that may include cough, shortness of breath, fever, muscle aches and headaches. (
  • Pontiac fever symptoms are primarily fever and muscle aches, as it is a milder infection than Legionnaires' disease. (
  • An acute or chronic localized infection which may or may not include symptoms of fever and muscle aches. (
  • This way, it is pretty similar to high-endurance physical exercises that boost the performance of skeletal muscles. (
  • Theophylline stimulates the CNS, skeletal muscles, and cardiac muscle. (
  • We hypothesized that HF patients would demonstrate improved locomotor blood flow with respiratory muscle unloading during activity. (
  • These data suggest HF patients preferentially steal blood flow from locomotor muscles to accommodate the work of breathing during activity. (
  • Further, HF patients are unable to vasoconstrict locomotor vascular beds beyond NB when presented with a respiratory load. (
