Obstructive sleep apnea (OSA) is a prevalent disorders characterized by intermittent obstructions of the upper airway during sleep. Continuous Positive Airway Pressure (CPAP) has been shown to be the most efficacious treatment for OSA. It consists of a small device that provides positive airway pressure delivered by a mask attached to the patients nose/mouth.
Obstructive sleep apnea (OSA) is inherently site-specific. In a physiological controlled intervention study, the investigators seek to determine whether applying expiratory resistance can acutely improve ventilation and sleep in patients with expiratory flow limitation (EFL).
Single center clinical study for the BONGO NASAL EPAP device in the treatment of obstructive sleep apnea for the purpose of obtaining safety and efficacy data
The aim of this post market study is to assess the impact of sleep-disordered breathing on the well-being of patients according to the treatment chosen, i.e. with or without implantation of the remedē® system to treat sleep-disordered breathing.
Evaluation of the add-on effect on endothelial dysfunction of treatment of periodontitis in patients with chronic periodontitis and severe obstructive sleep apnea treated by CPAP. Patients with and without chronic periodontitis will be treated by CPAP for 20 weeks. At V2 (10 weeks), endothelial dysfunction will be assessed by the Reactive Hyperemia- Peripheral Artery Tone index. The endothelial dysfunction of the patients will be also assessed at V3 (20 weeks) after periodontitis treatment for the group of patients with chronic periodontitis.
To assess the incidence of Sleep Apnea-Hypopnea Syndrome (SAHS), both obstructive and central, in patients with: 1) pacemaker indication; 2) implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRTD), 3) heart failure and preserved left ventricular ejection fraction (LVEF) and 4) heart failure and reduced LVEF.
The purpose of study is to evaluate the physiologic effects of pulmonary tissue/structural changes associated with COPD and upper airway inflammation on upper airway collapsibility. Upper airway collapsibility is closely associated with development of obstructive sleep apnea (OSA), which is a common disease characterized by repetitive collapse of upper airway during sleep, leading to hypoxemia and arousal. OSA has important neurocognitive and cardiovascular consequences, especially in patients with COPD. Participants in this research study will undergo two overnight sleep studies (PSGs), pulmonary function test, and CT scan of the upper airway and chest. The first sleep study will evaluate the sleep breathing disorder and the second sleep study will measure the upper airway collapsibility, called critical closing pressure (Pcrit). Pcrit is measured by a modified continuous positive airway pressure (CPAP) machine which can provide a wide range of pressures between 20 and -20 cmH2O in order to modify upper airway pressure.
The presence of Obstructive Sleep Apnea Syndrome (OSAS) has a high frequency in patients victims of a coronary artery disease (CAD) (myocardial infarction, revascularization). Unlike patients seen in a sleep Laboratory with an impact on daytime functioning, CAD apneic patients do not complain in their daytime functioning. The objective of this study is to explore whether the objective cognitive assessment measures may be a good marker of the efficacy of CPAP treatment given to non-sleepy apneic CAD patients. Coronary patients with an AHI between 15 and 40 / h will be treated (or not) after randomization with CPAP treatment. The expected results are: CPAP apneic coronary patients should have a positive impact on cognitive performance, particularly on attention span and working memory measured by improvement in the Paced Auditory Serial Addition Test score (PASAT score).
The purpose of this study is to determine whether modafinil use in patients with obstructive sleep apnea will improve postoperative delayed emergence after general anesthesia.
