• abstract: Obstructive sleep apnea (OSA) is a sleep disorder with growing prevalence and pathologically related to chronic and cardiovascular diseases. Patients with OSA syndrome can be improved by proper treatments but most of them remain undiagnosed until they're severely affected by complications. To evaluate OSA risk like what clinical polysomnography (PSG) test does, we developed a wearable solution based on CMOS imaging sensor (PAH8151HU, PixArt Imaging Inc.). Photoplethysmography was recorded by a wrist wearing sensor and processed by our OSA risk evaluation algorithm for biometric parameters calculation. Twenty-four subjects were included in this study. The overnight sleeping data were collected by our device and the benchmark medical certificated portable PSG device (ApneaLink Air, ResMed) simultaneously. The result of our algorithm derived OSA Level Index (OLI) is highly correlated (r = 0.9607) to the Risk Index (RI) of benchmark device. The diagnostic accuracy was great on clinical important OSA subjects. In addition to blood oxygen level (SpO2), which commercial wearables usually use, more information is analyzed in our works to meet the result of PSG. An optical sensor is the only thing we need to check the OSA risk with great reliability. The purposed solution provides a less distracted and more convenient way for domestic OSA risk evaluation.
