Effectiveness of Audio Cues to Achieve Positional Therapy in Patients With Positional Obstructive Sleep Apnea

Patients with obstructive sleep apnea (OSA) often experience more frequent and severe breathing disturbances when sleeping in the supine (back-sleeping) position compared with non-supine positions. Positional therapy aims to reduce time spent sleeping in the supine position, but existing treatment options may be limited by comfort and effectiveness. This study evaluates the effectiveness and usability of WhisperPT, an investigational in-ear positional therapy device that delivers gentle audio cues during sleep to encourage participants to move from the supine to a non-supine sleeping position. The study will assess the device's ability to reduce the apnea-hypopnea index (AHI), decrease time spent sleeping supine, and evaluate participant comfort and ease of use.
