Filter by:Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. In this protocol the investigators will test the effect of DAW1033B2 administered before sleep on OSA phenotype traits and OSA severity during sleep.
This multi-center observational study will prospectively collect data from patients who have an indication for servo ventilation therapy. This registry is intended to characterize the patient populations that may benefit from DreamStation BiPAP autoSV therapy (PR DS-autoSV, Philips Respironics, Monroeville, PA) in real life settings. In addition, this registry will assess adherence to the PR DS-autoSV therapy, the therapeutic benefits, collect morbidity and mortality data of servo ventilation in patients with central sleep apnea (CSA) and complex sleep-disordered breathing (SDB).
To assess the diagnostic validity and cost-effectiveness of a APNiA device, a home respiratory polygraphy (HRP).
This investigation is a prospective, non randomized, non blinded study. This investigation is designed to evaluate the performance, comfort and ease of use with the F&P trial nasal mask amongst Obstructive Sleep Apnea (OSA) patients.
The objective of this prospective cohort study is to determine the prevalence of obstructive sleep apnoea (OSA) in patients with and without thoracic aortic aneurysm.
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. In this protocol the investigators will test the effect of DAW1033D administered before sleep on OSA phenotype traits and OSA severity during sleep.
This study is a randomized controlled trial (RCT) to test two sleep apnea education programs for women Veterans newly diagnosed with sleep apnea (SA) who are prescribed positive airway pressure (PAP) therapy. This education program is designed to improve participants' sleep quality and help them to adjust to PAP therapy. Participants undergo a sleep and health assessment that is performed prior to beginning the education program. This assessment includes wearing a wrist actigraph to measure sleep and wake periods for 7 days and nights, and answering questionnaires about sleep habits and health. Participants are randomly assigned to one of two 6-week programs (intervention or educational control) provided by a study interventionist. Follow-up sleep and health assessments will be conducted at the end of the 6-week program and 3-months later. PAP usage data will be collected remotely for 6-months from PAP therapy initiation.
The aim of this study is to evaluate the effectiveness and safety of cNEP (continuous negative external pressure) for the treatment of obstructive sleep apnea during two weeks of home use in subjects of Japanese ethnicity.
Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults that has been strongly associated with various forms of cardiovascular disease. Compared to the general population, OSA occurs more often in patients with acute coronary syndrome (ACS). Although percutaneous coronary intervention (PCI) is nowadays part of standard therapy and optimal medical therapy has been used to manage traditional risk factors, the long-term cardiovascular outcomes after index ACS remain suboptimal. Some preliminary data suggest OSA is associated with higher risk of subsequent cardiovascular events in ACS patients. However, the study population was heterogeneous and these studies were not done in the context of new-generation drug-eluting stents and intensive antiplatelet therapy, thus precluding definite conclusions. Furthermore, a cardioprotective role of OSA in the context of acute myocardial infarction (AMI), via ischemic preconditioning, has also been postulated. Due to the inconsistent evidence, the investigators performed a large-scale, prospective cohort study to delineate the whole picture of the association of OSA with short- and long-term outcomes of patients with ACS. Whether treatment of OSA (eg. continuous positive airway pressure (CPAP)) would prevent these events will also be evaluated. Moreover, the investigators will assess the potential mechanisms of OSA-induced atherosclerosis and myocardial injury in ACS patients.
A new, well-tolerated treatment for obstructive sleep apnea - tongue stimulation - is a device which opens the airway during sleep and can provide treatment for patients unable to use the mask and hose treatment. The study will evaluate the effect of this new treatment on blood pressure and heart-related measures to see if it lowers patients' risk of heart problems.
