1. A system comprising:
- a respiration-based apnea detector configured to receive cyclic information indicative of inhalation or exhalation;
a non-respiration-based apnea detector configured to receive information other than cyclic information indicative of inhalation or exhalation; and
an apnea classifier module, coupled to the respiration-based and non-respiration-based apnea detectors, configured to distinguish between obstructive sleep apnea (OSA) and central sleep apnea (CSA) using information from both the respiration-based and non-respiration-based apnea detectors.

Abstract
An apnea classification system provides for apnea monitoring and differentiation based on several sleep apnea related parameters for diagnostic and therapeutic purposes. Monitoring of such sleep apnea related parameters allows the apnea classification system to differentiate among the different types of apnea. This information may then be used to determine the best method of therapy, or adjust current therapy parameters to more effectively treat a subject.

12. A method to distinguish between obstructive sleep apnea (OSA) and central sleep apnea (CSA), the method comprising:
-
receiving cyclical information indicative of inhalation or expiration; receiving information other than cyclical information indicative of inhalation or exhalation; and using an apnea classifier module, distinguishing between obstructive sleep apnea (OSA) and central sleep apnea (CSA) using the cyclical information indicative of inhalation or expiration and the information other than cyclical information indicative of inhalation or exhalation. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system comprising:
-
a respiration-based apnea detector configured to receive cyclic information indicative of inhalation or exhalation; a non-respiration-based apnea detector configured to receive information other than cyclic information indicative of inhalation or exhalation; and an apnea classifier module, coupled to the respiration-based and non-respiration-based apnea detectors, configured to detect an apnea episode using the respiration-based apnea detector and to distinguish between obstructive sleep apnea (OSA) and central sleep apnea (CSA) using information from the non-respiration-based apnea detector during the detected apnea episode.
