Comparison of WatchPAT to polysomnography measurement of apnea-hypopnea index and obstructive sleep apnea severity in adolescents with overweight and obesity

The prevalence of obstructive sleep apnea (OSA) increases dramatically in adolescents with overweight or obesity. The gold standard for diagnosis of OSA is in-laboratory polysomnography (PSG). However, access to PSG can be challenging, necessitating development of alternative devices. This study aimed to compare the accuracy of WatchPAT, a device that indirectly detects apnea and hypopnea events through peripheral arterial tonometry, to PSG in adolescents with overweight and obesity.
