Have you been diagnosed with obstructive sleep apnea (OSA) and been referred to the Yale New Haven Hospital Sleep Center for continuous positive airway pressure (CPAP) treatment? This study is examining how the features that can raise or lower the risk of OSA can impact how well CPAP works in an individual. Researchers will use detailed sleep studies to determine which features contribute to OSA. Results from this study will help researchers develop treatment plans that can lead to personalized OSA treatments to improve patient lives. To participate in this study, you must be at least 19 years old. This study takes place in North Haven, Connecticut.
