System and method for discrimination of central and obstructive disordered breathing events
First Claim
1. A method for classifying disordered breathing in a patient, comprising:
- detecting a disordered breathing event;
sensing motion associated with respiratory effort during the disordered breathing event; and
classifying the disordered breathing event based on the sensed motion, wherein at least one of detecting, sensing, and classifying is performed at least in part implantably.

Abstract
Disordered breathing events may be classified as central, obstructive or a combination of central an obstructive in origin based on patient motion associated with respiratory effort. Central disordered breathing is associated with disrupted respiration with reduced respiratory effort. Obstructive disordered breathing is associated with disrupted respiration accompanied by respiratory effort. A disordered breathing classification system includes a disordered breathing detector and a respiratory effort motion sensor. Components of the disordered breathing classification system may be fully or partially implantable.
