Correntropy-Based Pulse Rate Variability Analysis in Children with Sleep Disordered Breathing

Abstract: Pulse rate variability (PRV), an alternative measure of heart rate variability (HRV), is altered during obstructive sleep apnea. Correntropy spectral density (CSD) is a novel spectral analysis that includes nonlinear information. We recruited 160 children and recorded SpO 2 and photoplethysmography (PPG), alongside standard polysomnography. PPG signals were divided into 1-min epochs and apnea/hypoapnea (A/H) epochs labeled. CSD was applied to the pulse-to-pulse interval time series (PPIs) and five features ext… Show more

“…The classifier obtained an AUC of 82.12%, which is higher than other PPG-based methods in the literature such as [6] where an AUC of 72% was reported. Still, the obtained Acc was 72.66%, similar to the 69% reported in [6].…”

“…The classifier obtained an AUC of 82.12%, which is higher than other PPG-based methods in the literature such as [6] where an AUC of 72% was reported. Still, the obtained Acc was 72.66%, similar to the 69% reported in [6]. This Acc is low for clinical diagnosis purposes but it is interesting for screening purposes taking into account the convenience of PPG signal for such devices.…”
