NONCONTACT DETECTION METHOD OF SLEEP STAGES AND SLEEP-DISORDERED BREATHING

摘要

A noncontact method for detecting and monitoring sleep-disordered breathing includes the following steps: (1) during a test, a tested person lies in a bed, and the antennas of a wireless transceiver are aligned to the human body; (2) the wireless transceiver has the received signal to be subjected to digital signal processing, and mode recognition, and records and reports disordered events. Such non-contact measurement can simplify operation and facilitate long-term dynamic monitoring.
