Abstract
Aspects of the present disclosure are directed to detecting apneic and/or hypopneic events, utilizing a physiological signal. Various apparatuses and/or methods involve computing time series of interbeat intervals are from data characterizing activity of a beating heart, decomposing the time series is into subcomponents, and identifying ones of the subcomponents that relate to a portion of the data during which an apneic and/or hypopneic, as may be detected via oximetry. Once identified, these subcomponents and related formula/weighting can be utilized in computing further subcomponents from the data, and identifying further apneic and/or hypopneic events therefrom. In this context, such events may be detected without necessarily involving further use of oximetry.
