View clinical trials related to Obstructive Sleep Apnea (OSA).
Filter by:The primary objective of this project is to compare a health care delivery model, Direct Referral for Apnea Monitoring (DREAM), with initial in-person (Traditional) clinic appointments for Veterans at risk for obstructive sleep apnea (OSA). A secondary objective is to determine the negative predictive value (NPV) of home sleep apnea testing (HSAT).
This study will take between 1-2 months (with first patient first visit to last patient last visit). Each participant will use the supplied PAP device and mask for a period of up to 14 nights. Participants will complete a series of questionnaires. The study will collect data to support the development of an advance leak detection technology.
This is a post-marketing surveillance study to investigate the efficacy and safety of the Negative Pressure Sleep Therapy System for the treatment of obstructive sleep apnea.
The investigators hypothesize that chemoreflex response of muscle sympathetic nerve activity (MSNA) during hypoxia and hypercapnia will be increased in coronary artery disease (CAD) patients and that the presence of obstructive sleep apnea (OSA) will potentiate these responses. And, that the exercise training would decrease the chemoreflex response of MSNA in these patients.
This study will test the hypothesis that the modified positive airway pressure (PAP) device for OSA will be no worse than a market released product in terms of its treatment efficacy, comfort and patient compliance. Patients will have their treatment pressure titrated using polysomnography (PSG) in the sleep laboratory, and then in a random order will spend additional time undergoing PSG using both devices, and using both devices at home for 3 weeks. Data will be collected from the PSG studies, device downloads, independent pressure-flow loggers, and custom questionnaires.
