Abstract

STUDY OBJECTIVES: To validate EnsoSleep photoplethysmography (ePPG) software as a medical device (SaMD) for home sleep apnea testing compared to polysomnography. METHODS: Simultaneous polysomnography (PSG) and photoplethysmography (PPG) signals were recorded for a single night in 225 individuals at risk for obstructive sleep apnea (OSA). PSG was scored by three registered polysomnographic technolo…
