Title: METHOD AND DEVICE FOR DETECTING OSAHS
Abstract:
Provided are a method and device for detecting OSAHS. The method comprises: acquiring a vibration signal of a subject during sleep, and determining a breathing signal of the subject (S1), wherein the breathing signal comprises an inspiration signal generated upon inspiration and an expiration signal generated upon expiration; acquiring strength of a first vibration signal within a specified frequency range and superimposed on the inspiration signal, and strength of a second vibration signal within a specified frequency range and superimposed on the expiration signal adjacent to the inspiration signal (S2); and comparing, according to a preset method, the strength of the first vibration signal with the strength of the second vibration signal, and determining, according to a comparison result, whether the subject is snoring (S3). Since the detection is performed synchronously with breathing, the invention can prevent interference caused by coughing, speaking and other acoustic signals transmitted in the air, thereby significantly increasing accuracy in determining OSAHS. Moreover, the method and device of the invention can be realized by only making a minor modification to software in existing sleep sensors without incurring additional hardware costs.
