Claim One:
1. A method of operating an implantable device to classify disordered breathing events of a patient, comprising: sensing respiration with a respiration sensor and generating a respiration signal indicating patient respiration cycles; sensing chest wall motion with a motion sensor and generating a motion signal indicating chest wall motion associated with inspiratory effort; detecting disordered breathing based on the respiration signal using a disordered breathing detector; time correlating the motion signal with the respiration signal using a processor of the implantable device; classifying the disordered breathing event as a central disordered breathing event in response to the motion signal remaining below a motion threshold during a time period in which the respiration signal remains below an inspiration threshold; or classifying the disordered breathing event as an obstructive disordered breathing event in response to the motion signal rising above the motion threshold during a time period in which the respiration signal remains below the inspiration threshold; and delivering a therapy to treat disordered breathing based on the classification of the disordered breathing event with a therapy delivery unit coupled to the processor.
