  • APPARATUS AND METHOD FOR EVALUATING OBSTRUCTIVE SLEEP APNEA WITH PPG SIGNAL
    Publication number: 20230181103
    Abstract: An apparatus and method for evaluating obstructive sleep apnea with PPG signal are provided. Measured heartbeat interval signal is used to evaluate whether there is obstructive apnea. The system includes a motion sensor for detecting whether a user is in a stationary state; an optical sensor for measuring the heartbeat interval signal of the user in a stationary state; a microprocessor for processing the heartbeat interval signal of the user to obtain an apnea parameter; an alert module for receiving the apnea parameter and feeding them back to the user; and a memory module for storing the apnea parameter after the signal processing. The system and method are used to determine whether the heartbeat interval signal is an obstructive sleep apnea signal, and further determine whether the user is in an obstructive sleep apnea situation.
