METHOD AND SYSTEM FOR SLEEP DETECTION

摘要

Described herein are various embodiments of a method and system for sleep detection. For example, in one embodiment, a method is described for automatically characterizing digitized breath sounds recorded from a subject over time as indicative of the subject being one of asleep and awake. This method comprises identify individual breathing cycles in a given segment of the recorded breath sounds; calculating one or more preset breathing cycle characteristics from the identified breathing cycles; evaluating a relative regularity of the calculated characteristics for the given segment; and upon the relative regularity satisfying a preset high regularity condition, outputting a sleep status indicator that the subject was likely asleep during the segment, otherwise outputting a wake indicator that the subject was likely awake during the segment.

1. A method for automatically characterizing digitized breath sounds recorded from a subject over time as indicative of the subject being one of asleep and awake, the method comprising:
identify individual breathing cycles in a given segment of said recorded breath sounds; calculating one or more preset breathing cycle characteristics from said identified breathing cycles; evaluating a relative regularity of said calculated characteristics for said given segment; and upon said relative regularity satisfying a preset high regularity condition, outputting a sleep status indicator that the subject was likely asleep during said segment; otherwise or upon said relative regularity satisfying a preset low regularity condition, outputting a wake indicator that the subject was likely awake during said segment.
