A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)

nCPAP improves abnormal autonomic function in at-risk-for-SIDS infants with OSA. (1/875)

We evaluated cardiovascular autonomic control and arousability during sleep in infants with obstructive sleep apnea (OSA) before and after 10 +/- 4 (mean +/- SD) days of treatment with nasal continuous positive airway pressure (nCPAP). Six OSA infants and 12 age-matched control infants were studied with polygraphic sleep studies at the age of 13 +/- 4 wk. During the study, 45 degrees head-up tilt tests were performed in slow-wave and rapid eye movement sleep. Blood pressure (BP) and heart rate (HR) were continuously monitored. All OSA infants had decreased initial BP and HR responses, followed by hypotension in two and hypertension in two. OSA infants displayed higher arousal thresholds in response to the tilt in rapid eye movement sleep (P < 0.005) and higher baseline HR (P < 0.05) than controls. nCPAP treatment normalized BP and HR responses as well as arousal thresholds to tilting and stabilized HR levels. OSA in infants may be linked with cardiovascular autonomic control disturbances and decreased arousability during sleep. These defects are improved by control of OSA with nCPAP.  (+info)

Effects of continuous positive airway pressure/positive end-expiratory pressure and pressure-support ventilation on work of breathing, using an animal model. (2/875)

OBJECTIVE: Evaluate the effects of continuous positive airway pressure (CPAP)/positive end-expiratory pressure (PEEP) and pressure support ventilation (PSV) on work of breathing (WOB). METHODS: With 13 anesthetized lambs we measured WOB with an esophageal balloon and flow signals. All the animals were sedated, intubated, and ventilated, using 2 pediatric ventilators (Servo 300 and VIP Bird). Ventilator settings were CPAP of 0, 5, and 10 cm H(2)O and PSV of 5 and 10 cm H(2)O with PEEP of 0, 5, and 10 cm H(2)O. Data were analyzed with 2-way analysis of variance. RESULTS: With the Servo 300 the total WOB (WOB(T)) increased between CPAP/PEEP of 0 and 10 cm H(2)O (p +info)

Leptin and ghrelin levels in patients with obstructive sleep apnoea: effect of CPAP treatment. (3/875)

Serum leptin and ghrelin levels were investigated in patients with obstructive sleep apnoea (OSA) syndrome before and during continuous positive airways pressure (CPAP) treatment and compared with body mass index (BMI)-matched controls without OSA. Male patients (n=30) with OSA (apnoea/hypopnoea index=58+/-16, BMI=32.6+/-5.3 kg x m(-2)) underwent CPAP treatment. Fasting leptin and ghrelin were measured at baseline and 2 days, and in the case of leptin 2 months after initiation of treatment. Baseline plasma ghrelin levels were significantly higher in OSA patients than in controls. After 2 days of CPAP treatment, plasma ghrelin decreased in almost all OSA patients (n=9) to levels that were only slightly higher than those of controls (n=9). Leptin levels did not change significantly from baseline after 2 days of CPAP treatment, but were higher than in the control group. After 8 weeks, leptin levels decreased significantly, although the BMI of the patients showed no change. The decrease in leptin levels was more pronounced in patients with a BMI <30 kg x m(-2). These data indicate that the elevated leptin and ghrelin levels are not determined by obesity alone, since they rapidly decreased during continuous positive airways pressure therapy.  (+info)

Heated humidification of nasal continuous positive airway pressure (nCPAP) reduces upper airway symptoms and improves initial use in obstructive sleep apnoea syndrome (OSAS). The present study aimed to assess the effect of heated humidification of nCPAP on upper airway symptoms and initial use in obstructive sleep apnoea. This study was of a randomised, crossover design. Subjects with polysomnographically confirmed OSAS were randomised to 3 weeks nCPAP treatment with heated humidification (nCPAP-humid) or placebo humidification (nCPAP pl-humid). Objective and subjective nCPAP use, upper airway symptoms, and treatment satisfaction were compared. Thirty seven of 42 patients completed the protocol. nCPAP-humid reduced the frequency of adverse upper airway symptoms. nCPAP use over 3 weeks was greater with nCPAP-humid compared with nCPAP pl-humid. No difference was found between the treatment arms in terms of subjective treatment satisfaction or alertness. Heated humidification of nasal continuous positive airway pressure reduces upper airway symptoms and is associated with a small increase in initial use but not subjective sleepiness or treatment satisfaction. The results support the use of heated humidification as a strategy to reduce side-effects related to continuous positive airway pressure but not routine initial use.  (+info)

Control of upper airway muscle activity in younger versus older men during sleep onset. (5/875)

Pharyngeal dilator muscles are clearly important in the pathophysiology of obstructive sleep apnoea syndrome (OSA). We have previously shown that the activity of both the genioglossus (GGEMG) and tensor palatini (TPEMG) are decreased at sleep onset, and that this decrement in muscle activity is greater in the apnoea patient than in healthy controls. We have also previously shown this decrement to be greater in older men when compared with younger ones. In order to explore the mechanisms responsible for this decrement in muscle activity nasal continuous positive airway pressure (CPAP) was applied to reduce negative pressure mediated muscle activation. We then investigated the effect of sleep onset (transition from predominantly alpha to predominantly theta EEG activity) on ventilation, upper airway muscle activation and upper airway resistance (UAR) in middle-aged and younger healthy men. We found that both GGEMG and TPEMG were reduced by the application of nasal CPAP during wakefulness, but that CPAP did not alter the decrement in activity in either muscle seen in the first two breaths following an alpha to theta transition. However, CPAP prevented both the rise in UAR at sleep onset that occurred on the control night, and the recruitment in GGEMG seen in the third to fifth breaths following the alpha to theta transition. Further, GGEMG was higher in the middle-aged men than in the younger men during wakefulness and was decreased more in the middle-aged men with the application of nasal CPAP. No differences were seen in TPEMG between the two age groups. These data suggest that the initial sleep onset reduction in upper airway muscle activity is due to loss of a 'wakefulness' stimulus, rather than to loss of responsiveness to negative pressure. In addition, it suggests that in older men, higher wakeful muscle activity is due to an anatomically more collapsible upper airway with more negative pressure driven muscle activation. Sleep onset per se does not appear to have a greater effect on upper airway muscle activity as one ages.  (+info)

Effect of continuous positive airway pressure treatment on elderly Chinese patients with obstructive sleep apnea in the prethrombotic state. (6/875)

OBJECTIVES: To characterize the prethrombotic state (PTS) in elderly Chinese patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and the effect of nasal continuous positive airway pressure (nCPAP) ventilation on their PTS. METHODS: Forty-one elderly patients with moderate and severe OSAHS were enrolled into the OSAHS group and underwent nCPAP treatment. Their blood samples were drawn at 6:00 am and 4:00 pm before and during nCPAP treatment, respectively, to test hemocrit, platelet aggregation (PAG), whole blood viscosity (WBV), plasma fibrinogen (fng), prothrombin time (PT) and activated partial thromboplastin time (APTT). All blood factors were also tested in a control group consisting of 32 healthy elderly Chinese with neither OSAHS nor cerebrocardiac vascular disease. RESULTS: In the OSAHS group there was a significantly higher hemocrit, WBV, fng, and a significantly shorter PT and APTT at 6:00 am compared to 4:00 pm before nCPAP treatment, while there was no significant difference among all blood test factors between 6:00 am and 4:00 pm on day 30 of the nCPAP treatment. In the OSAHS group, the hemocrit, WBV, PAG and plasma fng were significantly lower and the PT and APTT were significantly longer at 6:00 am on day 30 of the nCPAP treatment compared to 6:00 am before the nCPAP treatment. A significantly lower hemocrit, but a much longer PT and APTT were observed at 4:00 pm on day 30 of the treatment, compared with 4:00 pm before the treatment. No significant difference among the blood test factors was found between 6:00 am and 4:00 pm blood in the control group or between the control and OSAHS groups after 30 days of nCPAP treatment. CONCLUSION: In elderly Chinese OSAHS patients, PTS could be effectively eliminated by nCPAP treatment.  (+info)

Non-invasive ventilation in acute respiratory failure: a randomised comparison of continuous positive airway pressure and bi-level positive airway pressure. (7/875)

OBJECTIVES: To determine whether there is a difference in required duration of non-invasive ventilation between continuous positive airway pressure (CPAP) and bi-level positive airway pressure (BiPAP) in the treatment of a heterogeneous group of emergency department (ED) patients suffering acute respiratory failure and the subgroup of patients with acute pulmonary oedema (APO). Secondary objectives were to compare complications, failure rate, disposition, length of stay parameters, and mortality between the treatments. METHODS: This prospective randomised trial was conducted in the emergency departments of three Australian teaching hospitals. Patients in acute respiratory failure were randomly assigned to receive CPAP or BiPAP in addition to standard therapy. Duration of non-invasive ventilation, complications, failure rate, disposition, length of stay (hospital and ICU), and mortality were measured. RESULTS: 101 patients were enrolled in the study (CPAP 51, BiPAP 50). The median duration of non-invasive ventilation with CPAP was 123 minutes (range 10-338) and 132 minutes (range 20-550) for BiPAP (p = 0.206, Mann-Whitney). For the subgroup suffering APO, 36 were randomised to CPAP and 35 to BiPAP. For this group the median duration of non-invasive ventilation for CPAP was 123 minutes (range 35-338) and 133 minutes (range 30-550) for BiPAP (p = 0.320, Mann-Whitney). CONCLUSIONS: These results suggest that there is no significant difference in the duration of non-invasive ventilation treatment between CPAP and BiPAP when used for the treatment of acute respiratory failure in the ED. There was also no significant difference between the groups in secondary end points.  (+info)

A comparison of public and private obstructive sleep apnea clinics. (8/875)

The aim of the present study was to compare the clinical findings and polysomnography results obtained at public and private clinics in Brazil, the follow-up after diagnosis, and the therapeutic aspects related to continuous positive airway pressure. Patients who snore and who have obstructive sleep apnea were retrospectively divided into two groups, i.e., public clinic (N=307) and private clinic (N=317). Data concerning age, sex, body mass index (BMI), neck circumference, medical history, sleepiness scale, follow-up after diagnosis, and acceptance of continuous positive airway pressure therapy were collected. Mean age was 50 +/- 12 (range: 15-80) for public patients and 48 +/- 12 years (range: 19-91) for private patients. Mean BMI was 30 +/- 6 (range: 19-67) for public patients and 31 +/- 6 kg/m (range: 21-59) for private patients. The public clinic had a significantly higher frequency of women than the private clinic (M:F ratio of 2.0:1 and 6.9:1, respectively). The condition of private patients (apnea-hypopnea index=31 +/- 25) was more severe than that of public patients (apnea-hypopnea index=25 +/- 24 events/h; P=0.0004). In the public and private clinics, 19 and 15% of patients were snorers, respectively, and 81 and 85% of them had sleep apnea. After diagnosis, follow-up was longer in the private group. The continuous positive airway pressure acceptance was similar for both groups (32 vs 35%), but patients from the public clinic abandoned treatment more than private ones (65 vs 13%). Social status was significant in terms of the severity of obstructive sleep apnea age and gender distribution. Private patients look for a diagnosis earlier in the course of the disease than public patients, adhere more to follow-up, and abandon continuous positive airway pressure treatment less than public patients do.  (+info)

COVID-19 Impact is propelling the demand for continuous positive airway pressure (CPAP) devices. With an increase in cases of COVID-19 across the globe, there is a requirement for effective management of the infection using CPAP therapy. A shortage of ventilators during the COVID-19 pandemic has forced healthcare professionals to select alternative methods to deliver respiratory support to patients. Some of the modifications are required to convert CPAP devices to treat respiratory insufficiency, which helps to minimize aerosolization.. On the other hand, the high cost of device and maintenance along with high costs treatments are expected to limit the growth of global continuous positive airway pressure (CPAP) devices market. Also, infrastructural developments in the medical and healthcare industry in the field of continuous positive airway pressure (CPAP) devices market for sleep apnea treatment are expected to generate more opportunities for key players operating in the market..

TY - JOUR. T1 - The impact of continuous positive airway pressure on the lower esophageal sphincter. AU - Shepherd, K.. AU - Holloway, R.. AU - Hillman, D.R.. AU - Eastwood, Peter. PY - 2007. Y1 - 2007. N2 - The lower esophageal sphincter ( LES) is the primary barrier to gastroesophageal reflux. Reflux is associated with periods of LES relaxation, as occurs during swallowing. Continuous positive airway pressure ( CPAP) has been shown to reduce reflux in individuals with and without sleep apnea, by an unknown mechanism. The aim of this study was to determine the effect of CPAP on swallow- induced LES relaxation. Measurements were made in 10 healthy, awake, supine individuals. Esophageal ( Pes), LES ( Ples), gastric ( Pg), and barrier pressure to reflux ( Pb = Ples - Pg) were recorded using a sleeve catheter during five swallows of 5 ml of water. This was repeated at four levels of CPAP ( 0, 5, 10, and 15 cmH(2)O). Pressures were measured during quiet breathing and during the LES relaxation ...
BACKGROUND--Patients with the sleep apnoea/hypopnoea syndrome often receive continuous positive airway pressure to improve their symptoms and daytime performance, yet objective evidence of the effect of this treatment on cognitive performance is lacking. METHODS--A prospective parallel group study was performed comparing the change in objective daytime sleepiness as assessed by multiple sleep latency, cognitive function, and mood in 21 patients (mean (SE) number of apnoeas and hypopnoeas/hour 57 (6)) who received continuous positive airway pressure for three months and 16 patients (49(6) apnoeas and hypopnoeas/hour) who received conservative treatment for a similar period. RESULTS--Both groups showed significant within group changes in cognitive function between baseline and three months, but when comparisons were made between groups the only significant difference was a greater improvement in multiple sleep latency with continuous positive airway pressure. However, the improvement in sleep ...

Continuous positive airway pressure (CPAP) is a form of positive airway pressure ventilator, which applies mild air pressure on a continuous basis to keep the airways continuously open in people who are able to breathe spontaneously on their own. It is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent the lungs alveoli open and thus recruit more of the lungs surface area for ventilation. But while PEEP refers to devices that impose positive pressure only at the end of the exhalation, CPAP devices apply continuous positive airway pressure throughout the breathing cycle. Thus, the ventilator itself does not cycle during CPAP, no additional pressure above the level of CPAP is provided, and patients must initiate all of their breaths. CPAP typically is used for people who have breathing problems, such as sleep apnea. CPAP also may be used to treat preterm infants whose lungs have not yet fully developed. For example, physicians may use CPAP in infants with ...
The hypothesis for this study is that children with sleep disordered breathing will benefit from treatment with Continuous Positive Airway Pressure (CPAP) or Bi-level Positive Airway Pressure (BiPAP) in terms of reduction in cardiovascular risk markers and insulin resistance.. The CPAP machine delivers a predetermined level of pressure. It releases a stream of compressed air through a hose to the nose mask and keeps the upper airway open under continuous air pressure. This air pressure prevents obstructive sleep apnea, which occurs as a result of narrowing of the airway due to the relaxation of upper respiratory tract muscles during sleep. This machine helps to increase the oxygen flow by keeping the airway open.. The BiPAP machine delivers two levels of pressure. Inspiratory Positive Airway Pressure (IPAP) is a high amount of pressure, applied when the patient inhales and a low Expiratory Positive Airway Pressure (EPAP) during exhalation. ...
Obstructive sleep apnea is a relatively common disorder that can lead to lost productivity and cardiovascular disease. The form of positive airway treatment that should be offered is unclear. MEDLINE and the Cochrane Central Trials registry were searched for English language randomized controlled trials comparing auto-titrating positive airway pressure (APAP) with continuous positive airway pressure (CPAP) in adults with obstructive sleep apnea (inception through 9/2010). Six researchers extracted information on study design, potential bias, patient characteristics, interventions and outcomes. Data for each study were extracted by one reviewer and confirmed by another. Random effects model meta-analyses were performed for selected outcomes. Twenty-four randomized controlled trials met the inclusion criteria. In individual studies, APAP and fixed CPAP resulted in similar changes from baseline in the apnea-hypopnea index, most other sleep study measures and quality of life. By meta-analysis, APAP improved

N2 - Continuous positive airway pressure (CPAP) is used to prevent apneic arrest and/or hypoxia in patients suffering from obstructive sleep apnea. This modality has not been universally accepted for patients following upper gastrointestinal surgery because of concerns that pressurized air will inflate the stomach and proximal intestine, resulting in anastomotic disruption. This study was performed to assess the safety and efficacy of postoperative CPAP for patients undergoing a gastrojejunostomy as part of a Roux-en-Y gastric bypass (RYGB) procedure. A total of 1067 patients (837 women [78%] and 230 men [22%]) were prospectively evaluated for the risk ...
Background and Objective: Continuous positive airway pressure (CPAP) is a standard therapy for patients with moderate to severe obstructive sleep apnea (OSA). Increased demands for polysomnography (PSG) and CPAP titration have led to long waiting lists and high cost. CPAP prediction formulas derived from sleep and anthropometric parameters are used to set the initial CPAP level during CPAP titration. In the current study, we aimed to compare the pressure derived from prediction formulas with the pressure resulted from CPAP titration in a sample of Iranian patients.. Materials and Methods: In this cross-sectional study, 90 subjects with confirmed OSA in a full PSG who underwent CPAP titration in Baharloo Sleep Clinic, Tehran, Iran, during 2017, were enrolled. All of the participants had Respiratory Disturbance Index (RDI) ≥ 15 in their PSG test. Then, the optimal pressure obtained from manual CPAP titration was compared with the one calculated by different prediction formulas for each ...

Background: Previous studies showed that obstructive sleep apnea (OSA) is common in patients with heart failure (HF) and associated with poor cardiovascular outcomes. However, therapeutic impact of continuous positive airway pressure (CPAP) on mortality and morbidity remains unclear among patients with HF.. Methods: In a prospective cohort study, we examined 111 HF patients who underwent sleep study, and compared all-cause death and HF hospitalization rates among patients without OSA, those with untreated OSA (apnea-hypopnea index ≥ 10 per hr of sleep), and those with OSA treated by CPAP.. Results: Patients were divided into without OSA (N=32), untreated OSA (N=53) and treated OSA (N=26). During a median follow-up of 21±9 months, there was no death in those with treated OSA, while there was no significant difference in total death rate between those without OSA and with untreated OSA (log-rank test P=0.558). However, there were 52 (28%) all-cause deaths plus HF hospitalizations during ...

Our study demonstrated that zaleplon administered just before CPAP titration during split-night PSG improved initial sleep latency without affecting minimum oxygen saturation or resultant CPAP pressure. Contrary to our hypothesis, use of zaleplon did not result improvement in sleep efficiency or arousal indices, and thus perception of sleep quality during the PSG did not differ between the two groups. Although CPAP adherence was relatively high in both groups, use of zaleplon did not result in increased compliance. Improvements in OSA-related symptoms as measured by FOSQ and ESS were also similar in the zaleplon and placebo groups.. Our data conflict with Lettieris work involving the use of a hypnotic during CPAP titration. A retrospective assessment of 400 consecutive patients prescribed CPAP for OSA showed that of multiple parameters assessed, only age and use of a hypnotic (typically zolpidem) during the CPAP titration were associated with better short-term CPAP compliance.14 This ...

A system including methods and apparatus for treatment of a medical disorder such as obstructive sleep apnea or congestive heart failure. The system involves applying a gain to flow rate of pressurized gas delivered to a patient during inspiratory and/or expiratory phases of a respiratory cycle to deliver the pressurized gas in proportion to the respective gains during inspiration and/or expiration. A base pressure may be applied in addition to the gain-modified pressures and an elevated pressure profile may be employed to assist or control inspiration. The system may be fully automated responsive to feedback provided by a flow sensor that determines the estimated patient flow rate. A leak computer can be included to instantaneously calculate gas leakage from the system. The system may be utilized in connection with conventional continuous positive airway pressure treatments, such as CPAP or bi-level positive airway pressure equipment to effect various beneficial treatment applications.

Aim: Infants with viral bronchiolitis are often hospitalised with a proportion requiring respiratory support. The aim of this review was to examine the use of nasal prong continuous positive airway pressure (CPAP) as a management strategy for infants with a diagnosis of bronchiolitis, who required stabilisation and transport to a tertiary centre.. Method: A retrospective audit of infants with bronchiolitis requiring CPAP during transport between January 2003 and June 2007.. Results: Nasal CPAP was initiated in 54 infants with 51 of these (34 ex-preterm, 17 term) subsequently continuing on CPAP during retrieval. Mean CPAP pressure was 7 cmH2O. Oxygenation improved between stabilisation and the end of retrieval (P , 0.01). During retrieval, there was no significant increase in transcutaneous CO2, no infant required endotracheal ventilation and no adverse events were noted. Five infants were intubated within the first 24 h of admission at the receiving hospital.. Conclusion: This review ...

Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. With PEP, inspiratory pressure is negative, i.e. lower than ambient air pressure, as during a normal inspiration, but with CPAP, the inspiratory pressure is positive, i.e. higher than ambient air pressure.. Methods: This thesis is based on four separate studies in which four different breathing devices, a PEP-bottle (threshold resistor device), a PEP-mask (flow resistor device), a threshold resistor CPAP and a flow resistor device were investigated. Paper I, II and III are based on studies in healthy volunteers. Paper IV is a bench study performed in a hypobaric chamber. Paper I examined differences between two PEP devices, the PEP-bottle and the PEP-mask. Paper II evaluated the ...

Purpose: Recent guidelines for acute heart failure (AHF) support the use of continuous positive airway pressure (CPAP) although its early use upstream intensive care unit (ICU) requires more evidence. The aim of this multicenter randomized study was to compare the effects of standard treatment of cardiogenic acute pulmonary oedema to CPAP when started in out-hospital setting and continued in ICU.. Methods: AHF presenters with respiratory distress were enrolled by 10 emergency medical mobile services. Inclusion criteria were respiratory rate ,25, pulse oxygen saturation ,90% in air and Killip score ≥3. Each eligible patient was randomly assigned at home to receive standard treatment (ST) including oxygen, nitroglycerin, diuretic and inotropic drug as appropriate, or a combination of ST and CPAP (7.5-10 cmH2O). The primary end point, a composite of death, presence of intubation criteria or persistence at the second hour after inclusion, reappearance of the inclusion criteria or circulatory ...
CPAP treatment was associated with a reduction in the number of patients with unsustained AT (from 8 to 1, P=.024) and in the total number of AT beats (P=.026). In contrast, the number of VEs did not fall significantly (P=.44).. Two patients developed episodes of second-degree atrioventricular block. The use of CPAP in both patients resolved conduction changes and neither required pacemaker implantation. Two more patients had non-severe sinus dysfunction, which resolved in 1 of them after introduction of CPAP; neither required a pacemaker.. Subgroup Analysis. Patients over 50 years of age (n=17) had more disturbed baseline HRV figures than younger patients (P,.05) and their frequency domain parameters (VLF, LF and HF) during waking hours improved more significantly than the under-50 age group (P,.05). Age did not affect the incidence of arrhythmias, nor the influence of CPAP on this parameter. Arterial hypertension was more common in patients aged,50 years (14/17 vs. 3/9 patients, P=.03), and ...
Purpose: To investigate the impact of continuous positive airway pressure (CPAP) applied by a full-face fitted mask at 15 cmH2O on total cerebral blood flow (tCBF), jugular venous flow (tJVF) and cerebrospinal fluid (CSF) flow.. Materials and methods: Axial 2D phase-contrast MRI measurements were acquired at the C2-C3 vertebral level for 23 healthy male awake subjects at baseline (without) and with CPAP applied. CSF flow was quantified within the spinal subarachnoid space and tCBF was quantified based on the summation of blood flow within the left and right internal carotid and vertebral arteries. tJVF was quantified based on the summation of blood flow within the left and right jugular veins. Heart rate, transcutaneous carbon dioxide (PtcCO2) and oxygen saturation were continuously monitored during the MR protocol.. Results: CPAP decreased the pulse amplitude (PtPPA) of tJVF by 21% (p = 0.004). CSF stroke volume (SV) and PtPPA also decreased by 20% (p = 0.003) and 15% (p = 0.005), respectively. ...
OBJECTIVE: To compare the efficacy and safety of bubble continuous positive airway pressure (CPAP) and Infant Flow Driver (IFD) CPAP for the post-extubation management of preterm infants with respiratory distress syndrome (RDS). STUDY DESIGN: A total
Introduction Dynamic hyperinflation (DH) is characterised by an increase in end-expiratory lung volume (EELV) and contributes to exercise limitation in Chronic Obstructive Pulmonary Disease (COPD) patients. Neural respiratory drive (NRD) directly reflects the load-capacity relationship of the respiratory system and is therefore expected to increase with DH. However, there are limited data investigating the effects of isolated increases in EELV on NRD. We hypothesised that 1) increases in EELV induced by continuous positive airway pressure (CPAP) would increase NRD in healthy subjects and 2) with the change in lung volume, NRD to the parasternal intercostal muscles would increase to a greater extent than that to the diaphragm at higher levels of CPAP. ...

Positive airway pressure devices keep pressured air flowing through the airways of the throat and is one of the common treatments for sleep apnea.
Few comparative studies of nasal CPAP devices have been published. In particular, we are unaware of any studies that compare lung recruitment with different nasal CPAP devices as they are currently being used in infants. The main objective of this study was to compare the efficacy of 3 distinct devices-2 continuous flow devices and 1 variable flow device-in recruiting lung volume at various nasal CPAP levels.. Factors determining the effectiveness of any nasal CPAP device include its associated work of breathing, flow characteristics, ease of application, and the comfort level of the infant once the device is in place. Continuous flow nasal CPAP is increased or decreased by varying the resistance to exhalation at the exhalation valve on an infant ventilator. Nasal prongs are commonly used to provide continuous flow nasal CPAP. Concerns exist, however, about increased work of breathing with nasal prongs, compared with face mask CPAP.11Additionally, nasal prongs often become dislodged making care ...

In this study we found that treatment of OSA with CPAP did not result in a reduction in weight, and actually was associated with weight gain. This observation was independent of age, gender, race, OSA severity, and sleepiness. Furthermore, those with the greatest adherence to CPAP appeared to have gained the most weight.. The primary finding in this study is that CPAP treatment of OSA does not result in weight loss over a 6-month time frame. Our findings are therefore consistent with those of Redenius et al., who failed to observe in a retrospective study any reduction in weight in 183 CPAP treated patients followed in a sleep center over 10 to 14 months.12 Similarly, several smaller studies also have failed to find a change in weight with CPAP treatment. In a randomized controlled trial of sibutramine in comparison to CPAP for weight loss, CPAP treatment for one year in 18 patients was not associated with a change in weight.11 Similarly, addition of CPAP did not result in greater weight loss ...
Upper airway obstruction (UAO) is a major problem in unconscious subjects, making full face mask ventilation difficult. The mechanism of UAO in unconscious subjects shares many similarities with that of obstructive sleep apnea (OSA), especially the hypotonic upper airway seen during rapid eye movement sleep. Continuous positive airway pressure (CPAP) via nasal mask is more effective at maintaining airway patency than a full face mask in patients with OSA. We hypothesized that CPAP via nasal mask and ventilation (nCPAP) would be more effective than full face mask CPAP and ventilation (FmCPAP) for unconscious subjects, and we tested our hypothesis during induction of general anesthesia for elective surgery. In total, 73 adult subjects requiring general anesthesia were randomly assigned to one of four groups: nCPAP P0, nCPAP P5, FmCPAP P0, and FmCPAP P5, where P0 and P5 represent positive end-expiratory pressure (PEEP) 0 and 5 cm H2O applied prior to induction. After apnea, ventilation was initiated with
During the past three decades conflicting evidences have been published on the use of non-invasive ventilation (NIV) in patients with acute cardiogenic pulmonary edema (ACPE). The aim of this study is to describe the management of acute respiratory failure (ARF) due to ACPE in twelve Italian emergency departments (EDs). We evaluated prevalence, characteristics and outcomes of ACPE patients treated with oxygen therapy, continuous positive airway pressure (CPAP) or Bi-level positive airway pressure (BiPAP) on admission to the EDs. In this multicenter, prospective, observational study, consecutive adult patients with ACPE were enrolled in 12 EDs in Italy from May 2009 to December 2013. Three study groups were identified according to the initial respiratory treatment: patients receiving oxygen therapy, those treated with CPAP and those treated with BiPAP. Treatment failure was evaluated as study outcome. We enrolled 1293 patients with acute cardiogenic pulmonary edema. 273 (21%) began with oxygen, 788 (61%)

Continuous positive airway pressure (CPAP) is the most effective treatment for obstructive sleep apnea. CPAP involves wearing a mask that props open the airway and circulates air pressure during the night. Improvements have been shown across diverse sleep conditions (e.g., sleeping while watching an event, restless sleep) and quality of life measures after six months of CPAP treatment. Improvements in quality of life include in daily in functioning, social interactions, and emotional functioning. In addition, a lower incidence of hypertension was found in persons who were treated with continuous positive airway pressure (CPAP) (Marin et al., 2012). Treatments should last for at least 6 months. Below a treatment threshold, which may be longer for some patients, sleep apnea symptoms can return when treatment is stopped. Cranial facial structure abnormalities can require surgery. Participants in a survey of maxillomandibular advancement (MMA) over 53 studies, or 627 adults, reported improvements in ...

If these measures dont improve your sleep or if your apnea is moderate to severe, then your doctor may recommend other treatments. Certain devices can help open up a blocked airway. In other cases, surgery may be necessary.. Therapies: Positive airway pressure. If you have obstructive sleep apnea, you may benefit from positive airway pressure. In this treatment, a machine delivers air pressure through a piece that fits into the nose or is placed over the nose and mouth while you sleep. Positive airway pressure reduces the number of respiratory events that occur as you sleep, reduces daytime sleepiness and improves your quality of life.. The most common type is called continuous positive airway pressure, or CPAP (SEE-pap). With this treatment, the pressure of the air breathed is continuous, constant and somewhat greater than that of the surrounding air, which is just enough to keep your upper airway passages open. This air pressure prevents obstructive sleep apnea and snoring.. CPAP may be given ...

WEDNESDAY, Oct. 7, 2020 (HealthDay News) -- Continuous positive airway pressure treatment, commonly known as CPAP, can lower heart disease risk in people with prediabetes, according to a new study.. In prediabetes, blood sugar levels are above normal but not high enough to be considered diabetes. CPAP is used to treat obstructive sleep apnea, a disorder in which breathing repeatedly stops and starts during sleep. A CPAP machine uses a mask to deliver steady air pressure into a persons airway.. This new study found that, among people with prediabetes and sleep apnea, those who used CPAP for two weeks saw their resting heart rate fall by four to five beats per minute, compared to those who didnt use CPAP.. With optimal CPAP treatment, heart rates were not only lower at night but also during the day, according to the report published Oct. 1 in the Journal of the American Heart Association.. Thats significant, said study author Dr. Esra Tasali, director of sleep research at University of ...
Continuous positive airways pressure (CPAP) is the most common treatment for obstructive sleep apnoea. It involves the use of a pump which delivers low pressure air into the airways via tubing and a mask fitted to the nose. It is worn during sleep and delivers enough pressure to keep the airway open during sleep. The amount of pressure required to maintain an open airway varies with each individual. If the results of the sleep study clearly indicate OSA, a CPAP machine is often applied and adjusted to the appropriate settings while the study is in progress. It may be necessary to return to the sleep clinic after the study to receive training on how to properly use the CPAP machine at home. Many people find they feel much better within a few days of commencing CPAP as they get the benefit of deep restorative sleep that they previously lacked.. Variations of positive airways pressure therapy devices are auto-titrating CPAP, in which the levels of pressure are adjusted if the device senses ...

You can treat obstructive sleep apnea (OSA) at home if you have mild sleep apnea (5 or fewer apnea episodes per hour). Home treatment for sleep apnea includes: You can help to reduce sleep apnea symptoms by avoiding alcohol and sedatives. These relax the muscles in the back of your throat, making it harder for you to breathe. If you smoke, quit smoking. If you are overweight, lose weight. Sleep on your side instead of on your back. Sleep Apnea Treatment Treatment for sleep apnea includes lifestyle changes, continuous positive airway pressure (CPAP) (to prevent the airway from closing during sleep), and surgery. The goals of treatment are to relieve symptoms such as snoring and excessive daytime sleepiness and prevent other problems, such as high blood pressure. Continuous positive airway pressure (CPAP) is the most common treatment for sleep apnea. For this treatment, you wear a mask over your nose during sleep. The mask blows air into your throat at a pressure level that is right for you. The ...
The present study objective was to establish whether pretreatment social cognitive variables may contribute to the explanation of variance in adherence to continuous positive airway pressure (CPAP) treatment for patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS). A total of 119 of 180 consecutive OSAHS patients were recruited to the study prior to initial CPAP titration. Patients completed psychological measures of health value, health locus of control (incorporating internality, chance, powerful others) and self-efficacy prior to CPAP titration. Objective adherence data were measured by CPAP unit time clocks and collected at 3-month follow-up. Average nightly use was calculated over this period. Logistic regression of prospective predictors of adherence produced a model comprising psychological (health value, internality, powerful others), as well as clinical variables (Epworth score, body mass index, apnoea/hypopnoea index, CPAP pressure). This model explained 24% of the variance in

Treatment. Because obesity is the biggest risk factor for obstructive sleep apnea, weight loss is one of the main treatments. Patients should be counseled on healthy eating and exercise to achieve weight loss.. Continuous positive airway pressure therapy is another treatment for OSA. CPAP devices should be used regularly by patients. This is often a problem due to noncompliance as patients report that the masks are uncomfortable and loud, making it hard for them to sleep. It is important to emphasize the importance of daily use of CPAP with patients.. Surgical intervetions such as uvulopalatopharyngoplasty, craniofacial reconstruction, and tracheostomy may be necessary in rare cases of OSA.. References. ...
CPAP has become a widely accepted treatment in respiratory medicine for obstructive sleep apnea (OSA). With this study, Bersten and colleagues add evidence for the emerging role of CPAP in the treatment of acute pulmonary edema. Earlier work by Vaisanen and Rasanen showed a reduction of respiratory rate with CPAP, but no effect on PaO2 or PaCO2 (1). In the current study, however, significant improvement was seen in the respiratory rate as well as PaCO2, pH, and the PaO2 to FIO2 ratio within the critical first hour of treatment. This study shows that early implementation of CPAP can decrease both the need for intubation as well as length of stay in the intensive care unit (ICU) for a patient who develops acute pulmonary edema. Future studies should examine whether nasal CPAP affords the same benefit as mask CPAP in the treatment of acute pulmonary edema. The benefits of long-term nasal CPAP on left ventricular function in patients with OSA and congestive heart failure have been shown (2). Nasal ...

There is no gold standard technique to assess the sympathetic activity. The well-known, simple and cost-effective tool for noninvasive assessment of circulatory control is power spectral analysis of heat rate variability and blood pressure variability. However, these methods ignore the influence of respiration on R-R interval and systolic blood pressure power spectrum. A more precise separation of the effect of respiration and systolic blood to heart rate variability and noninvasive assessment of circulatory control using a minimal closed-loop modeling of circulatory control system was developed, and the effects of continuous positive airway pressure therapy on cardiovascular variability in adults with obstructive sleep apnea syndrome (OSAS) were successfully revealed.; In this research, in addition to the Laguerre functions, we have used the Meixner functions as another set of the basis functions. Moreover, an existing closed-loop minimal model of cardiovascular variability, modified to ...
Sleep apnea patients suffer from a variety of different symptoms, including difficulty breathing and trouble sleeping through the night. Dr. Kevin Sadati now offers the septoplasty turbinate reduction surgery as a solution to his patients who suffer from this disorder.. Many people associate sleep apnea with loud snoring, but the fact of the matter is Orange County patients with sleep apnea actually stop breathing when they enter deep sleep. This causes many different issues for the person who suffers from this disorder, including disrupted sleep and difficulty getting the fulfilling rest that they need. While the Continuous Positive Airway Pressure therapy, or CPAP, has commonly been used to treat sleep apnea, ENT surgeon Dr. Kevin Sadati has found that the septoplasty procedure can be an even better solution.. The septoplasty surgery is actually designed to correct a deviated septum in the nose. However, this same surgery also reduces the size of the nasal turbinate. Turbinate surgery can ...

The percentage of compliant continuous positive airway pressure (CPAP)-treated apnoeic patients that continue to experience residual excessive sleepiness (RES) is unknown. RES was defined by an Epworth Sleepiness Scale (ESS) score of |or=11. In total, 502 patients from 37 French sleep centres using CPAP |3 h night(-1) attending their 1-yr follow-up visit were eligible. ESS and polysomnographic data as well as symptoms, quality of life, depression scores and objective CPAP compliance at 1 yr were collected. Overall, 60 patients remained sleepy on CPAP (ESS 14.3+/-2.5) leading to a prevalence rate of RES of 12.0% (95% confidence interval (CI) 9.1-14.8). After having excluded associated restless leg syndrome, major depressive disorder and narcolepsy as confounding causes, the final prevalence rate of RES was 6.0% (95% CI 3.9-8.01). Patients with RES were younger and more sleepy at diagnosis. The relative risk of having RES was 5.3 (95% CI 1.6-22.1), when ESS before treatment was |or=11. Scores of emotional
Over the last decade, oral appliance use for the treatment of snoring, mild obstructive sleep apnea and for those patients who are intolerant of nasal continuous positive airway pressure has increased significantly. Obstructive sleep apnea is a progressive disease with serious cardiovascular and mortality consequences. The increased mortality is due not only to the progression of cardiovascular disease but also to judgement errors made while driving or operating machinery a result secondary to the excessive daytime sleepiness commonly seen in these patients. Canadian research has provided a significant amount of new knowledge in the field of obstructive sleep apnea. Recent findings have significantly increased our knowledge of how oral appliances should be used and which appliances are best suited to different patients.1,2 Titratable appliances, such as the 2 devices described by Dr. Tyler, allow for incremental advances of the mandible and permit some degree of lateral and vertical jaw ...
A translational preterm pig model analogous to infants born at 28 weeks of gestation revealed that continuous positive airway pressure results in limited lung recruitment but does not prevent respiratory distress syndrome (RDS); whereas, assist-control + volume guarantee (AC+VG) ventilation improves recruitment, but can cause injury, highlighting the need for improved ventilation strategies. We determined whether airway pressure release ventilation (APRV) can be used to recruit the immature lungs of preterm pigs without injury. Spontaneously breathing pigs delivered at 89% of term (model for 28 week infants) were randomized to 24 hours of APRV (n=9) versus AC+VG with a tidal volume of 5ml/kg (n=10). Control pigs (n=36) were provided with supplemental oxygen by an open mask. Nutrition and fluid support was provided throughout the 24-hour period. All pigs supported with APRV and AC+VG survived 24 hours, compared to 62% of control pigs. APRV resulted in improved lung volume recruitment compared ...
Many people impacted by sleep disorders use a CPAP, Continuous Positive Airway Pressure machine to regulate airflow and ensure continuous breathing. Although CPAP machines are effective at regulating breathing, many patients find it extremely difficult to sleep with a mask adhered to their face.. If you have Obstructive Sleep Apnea there is a much better solution. We provide an oral appliance alternative to the CPAP machine, and medical insurances can be billed for the device. If you have already had a sleep study and either cannot tolerate, or do not want a CPAP machine, this is a very effective alternative. This oral appliance gives a patient a restful night and the ability to travel.. As a member of the American Academy of Dental Sleep Medicine, I have extensive experience helping provide significantly improved quality of life for many patients. If you suffer from obstructive sleep apnea call my office, Portside Family Dental in Newburyport to schedule an appointment, 978-462-4590. A restful ...
Sleep apnea is recognized as a life-threatening condition, requiring prompt diagnosis and treatment. Snoring may be a prime symptom of sleep apnea.. If you have sleep apnea on your polysomnogram (sleep) study, you will have a CPAP test performed. Continuous Positive Airway Pressure (CPAP) is used primarily to treat obstructive sleep apnea, although there is evidence that it may be helpful in patients suffering from central apnea as well. CPAP involves the placement of a mask over the nose during sleep. An air compressor creates pressure that forces the air through the nasal passages to keep the airway open. This prevents snoring, airway obstruction, and drops in the oxygen level in the blood. This allows the patient to cycle normally through the different stages of sleep without awakening at night from a lack of oxygen, and to awaken in the morning feeling refreshed and alert during the day.. Bilevel therapy is similar to nasal CPAP, except that it delivers two different pressures: a higher ...
PURPOSE To describe the anesthetic management of a patient with previous left lower lobe resection who was submitted to a right upper lobectomy and review the changes in gas exchange and respiratory mechanics which occurred intraoperatively. CLINICAL FEATURES A 69-yr-old male with lung cancer, emphysema and obstructive sleep apnea, presented for a right upper lobectomy. His history was also positive for a left lower lobectomy six years previously. Intraoperative lung isolation was achieved using a 41 F left double-lumen tube (DLT). Monitoring the respiratory mechanics allowed for continuous adjustment of ventilator settings during the various phases of the surgery avoiding the risks of barotrauma and volutrauma. Problems with oxygenation occurred during one-lung ventilation. CONCLUSION This case report shows that a severe level of hypoxemia and hypercarbia associated to lung mechanical property changes can be observed during the OLV phase. Application of continuous positive airway pressure on the
The U.S. Food and Drug Administration has issued an Emergency Use Authorization (EUA) for the SCONE, for use by healthcare providers (HCP) as an additional layer of barrier protection in addition to personal protective equipment (PPE) to prevent HCP exposure to pathogenic biological airborne particulates by providing isolation of hospitalized patients with suspected or confirmed diagnosis of COVID-19, at the time of definitive airway management, when performing airway-related medical procedures, or during certain transport of such patients during the COVID-19 pandemic.. Authorized non-transport use of SCONE is only for definitive airway management (e.g., intubation, extubation and suctioning airways), when performing any airway-related medical procedures (e.g., high flow nasal cannula oxygen treatments, nebulizer treatments, manipulation of oxygen mask or continuous positive airway pressure/bi-level positive airway pressure [CPAP/BiPAP] mask use, airway suctioning, percussion and postural ...
Coronary artery disease (CAD) patients with obstructive sleep apnoea (OSA) have increased risk for major adverse cardiovascular and cerebrovascular events (MACCEs) compared with CAD patients without OSA. We aimed to address if the risk is similar in both groups when OSA patients are treated.. This study was a parallel observational arm of the RICCADSA randomised controlled trial, conducted in Sweden between 2005 and 2013. Patients with revascularised CAD and OSA (apnoea-hypopnoea index (AHI) ≥15 events·h−1) with daytime sleepiness (Epworth Sleepiness Scale score ≥10) were offered continuous positive airway pressure (CPAP) (n=155); CAD patients with no OSA (AHI ,5 events·h−1) acted as controls (n=112), as a randomisation of sleepy OSA patients to no treatment would not be ethically feasible. The primary end-point was the first event of MACCEs. Median follow-up was 57 months.. The incidence of MACCEs was 23.2% in OSA patients versus 16.1% in those with no OSA (adjusted hazard ratio 0.96, ...
Sleep disordered breathing represents a continuum, ranging from simple snoring sans sleepiness, upper‑airway resistance syndrome, obstructive sleep apnea (OSA) syndrome, to hypercapnic respiratory failure. Fifty seven articles formed the initial database and a final total of 50 articles were selected to form this review report. Four months were spent on the collection and retrieval of the articles. Articles were selected based on accuracy and evidence in the scientific literature. Oral appliances (OAs) are indicated for use in patients with mild to moderate OSA who prefer them to continuous positive airway pressure (CPAP) therapy, or for those who do not respond to, are not appropriate candidates for, or for those who have failed treatment attempts with CPAP. OAs protrude the mandible and hold it in a forward and downward position. As a consequence, the upper airway enlarges antero‑posteriorly and laterally, improving its stability. Although OA are effective in some patients with OSA, they ...
Background: Obstructive sleep apnea syndrome (OSAS) is a disease with metabolic consequences and is associated with decreased levels of insulin-like growth factor-1 (IGF-1).. Aim: To investigate whether continuous positive airway pressure (CPAP) increase IGF-1 in patients with OSAS.. Methods: Consecutive patients with OSAS were recruited from a sleep clinic and IGF-1 was measured before initiation of CPAP and at follow-up after 4.8±2.4 months. Patients compliant to CPAP treatment (usage ,4 hours/night) were compared with those considered to be non-compliant (usage ,4 hours/night).. Results: Complete data were obtained from 70 subjects (men 85.7%, age 55.8±11.9 years, apnea-hypopnea index (AHI) 42.5±21.1, Epworth sleepiness scale (ESS) 12.2±4.5). In those compliant to CPAP (n=41), there was an increase in IGF-1 with 22.1±25.3 ng/ml compared to 2.3±23.4 ng/ml in the non-compliant group (n=29) (P=0.0014). In multivariate analysis adjusting for gender, age, body mass index (BMI), average ...
