ABSTRACT:
Systems and methods are disclosd for detecting the recurrence of physiological functions. The disclosed systems and methods are especially adapted for detecting the recurrence of a patient's respiration from a signal representative of changes in the patient's thoracic volume, despite the presence of cardiovascular artifact in the signal. A cardiovascular artifact filter suppresses the artifacts in response to a signal, generated by a cardiotachometer, which varies as and is proportional to the fundamental frequency of each artifact.
