Background: To assess the clinical value of a wrist-worn device (Watch PAT100) to diagnose obstructive sleep apnea of geriatric patients in hospital.
Methods: The sleep parameters (RDI, AHI, sleep efficiency, and total sleep time), PSQI, and ESS were collected from 21 geriatric obstructive sleep apnea patients (mean age 58 years, 17 men, 4 women).
Sleep studies were done with Watch PAT100 under physician’s ssistance in well controlled hospital room. Analysis for sleep efficiency and total sleep time were carried out. Then correlations between sleep parameter and sleep questionnaire were analyzed.
Results: Mean sleep efficiency was 82.9% (72∼96), and mean total sleep time was 433.6 minutes(376∼472). PSQI correlated significantly with RDI (R=0.53, P=0.047), and ESS correlated significantly with AHI (R=0.606, P=0.024). No patients complained discomfort during sleep study and no patients were disturbed by equipment.
Conslusion: Hospital-based Watch PAT100 test can be easy and useful option in diagnosis of geriatric obstructive sleep apnea patients.
