Obstructive Sleep Apnea Syndrome analysis in children by Decreases in the Amplitude Fluctuations of Pulse Photoplethysmography: role of recording duration and Heart Rate Variability

Abstract

Heart rate variability (HRV) during Decreases in the Amplitude fluctuations of Pulse Photopletysmography signal events (DAP) is studied. The DAP duration and the time span of the polysomnography (PSG) recording under study are also considered for identification of Obstructive Sleep Apnea events in children. Oxygen desaturation is used as reference. The study involves recordings of 21 children.
