Abstract:
A CPAP apparatus is provided that determines the presence of a snore by the simplified method of using filtered expiratory noise as the measure of intrinsic device noise and comparing that to filtered inspiratory noise. The filtering time constants for inspiratory and expiratory noise are adjusted such that treatment pressure does not cause false snore detection.
