Detection of Sleep Apnea by Cyclic Variation of Pulse Rate

Published: Mar 1, 2019
Abstract
A variety of biosignal monitors provide pulse wave signal during sleep. This study examined if pulse rate fluctuation obtained from these signals can be used for detecting cyclic variation of heart rate (CVHR) that accompanies sleep apnea episodes during sleep. We found that the transfer function from heart rate to pulse rate in the very low-frequency band (0.0033-0.04 Hz) is a determinant of the ability of the pulse wave signal to detect...
