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 ...
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 ...

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 ▲]. Detailed reference viewed: 19 (1 ULiège) ...
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 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 ...
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 ...
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 ...

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 ...

Not much more extended or much more intense respiratory muscle education would bring about even bigger improvements in exercising functionality is uncertain,however the final results of this study suggest that this must be addressed.Cardiorespiratory responses to constant workrate physical exercise right after RMET Comparison of cardiorespiratory responses to CWE just before and immediately after RMET was performed to establish if any key cardiorespiratory variables changed in response towards the coaching stimulus. We located that VE and VO had been substantially higher in CWE soon after RMET. Our subjects kept their instruction regimen continual,with the exception of adding the RMET,as evidenced by standard evaluation of their each day workout logs. Therefore,alterations in the ventilatory response to CWE following RMET can be attributed to alterations within the functionality on the respiratory muscle tissues.Change in V E (Lmin,BTPS)Figure in VE with all the transform in efficiency time and ...
In Computer system air flow, both the inspiratory tension plus the inspiratory time are set and glued. This differs from BiPAP where the individual controls the inspiratory time. This modality may be useful within the neuromuscular illness patient who does not have the respiratory muscle mass toughness to generate an suitable inspiratory time. Placing a heightened inspiratory time may enhance the tidal quantity presented, nevertheless it may enhance individual-ventilator dyssynchrony if the established inspiratory time is extended compared to affected persons desired inspiratory time ...
Introduction Event-locked averaging of EEG recordings has demonstrated that preinspiratory potentials precede inspiration during respiratory-related cortical activation. However, this procedure relies on assumptions of on-going brain activity and is highly susceptible to low frequency artifacts. Frequency analysis is an alternative method of assessing EEG activity, but it is not known if this method can identify respiratory-related cortical activation. The aim of this study was to compare time-frequency maps during different respiratory tasks.. Methods Healthy subjects (n=6) performed 3 conditions: quiet breathing (QB), self-paced voluntary sniffs and ventilation with an inspiratory threshold load (ITL; ∼23 cmH20, range 18-25 cmH20). EEG recordings were made from 32 channels. Time-frequency maps were computed for each subject and condition for recordings from Fz, FCz, Cz, C3 and C4. Contrasts between conditions were performed by T score calculation with statistical analysis by clustering ...

To Familial Mediterranean Fever (FMF) is an autoinflammatory disorder with genetic origin. Pleuritis is most common in FMF. Long-term sequelae of respiratory system havent been described in FMF. We documented pulmonary manifestations in patient with FMF. A 61-year- old woman presented with dyspnea, unilateral chest pain, generalized myalgia and FMF. Physical examination was unremarkable. 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 ...
