Document Type and Number:
WIPO Patent Application WO/2023/048158
Kind Code:
A1
Abstract:
The present invention obtains biological vibration data from the heart rate, respiration, and body motion of a subject during sleep, performs frequency analysis on the acquired biological vibration data, and acquires any one among an average of the frequency spectrum at a location determined to be awakening, an average of the frequency spectrum at a location determined to be other than awakening, and an average of the frequency spectrum both at the location determined to be awakening and the location determined to be other than awakening. The present invention acquires an approximation curve for the logarithmic value of the obtained average of the frequency spectrum, and determines whether the subject suffers from sleep apnea syndrome on the basis of the unimodal characteristics of the logarithmic value of the average of the frequency spectrum.
