1. A method for delivering airway pressure to a patient, comprising:
- providing a patient-implantable cardiac rhythm monitoring system adapted to electrically couple to the patient'"'"'s heart and to communicate with a patient-external respiratory therapy device;
determining cardiac cycle phase using the cardiac rhythm monitoring system, including determining if the cardiac cycle phase is systole or diastole based on one or more of (a) implantably sensing a parameter indicative of the cardiac cycle phase, and (b) determining delivery of a cardiac pacing pulse; and
controlling the airway pressure delivered by the patient-external respiratory therapy device in synchrony with the cardiac cycle phase, wherein controlling the airway pressure is performed at least in part implantably.

Abstract
Methods and systems involve adjusting respiratory therapy based on cardiac cycle phase. A parameter indicative of cardiac cycle is sensed and the respiratory therapy is adjusted based on cardiac cycle phase. Modulation of respiratory therapy pressure reinforces the pumping action of the heart and results in increased cardiac output with decreased expenditure of myocardial energy output.

23. A system for controlling delivery of airway pressure to a patient, comprising:
-
a patient-implantable pulse generator configured to deliver cardiac pacing pulses to a patient'"'"'s heart based on cardiac pacing information; patient-implantable cardiac rhythm monitoring system means for electrically coupling to the patient'"'"'s heart and for communicating with a patient-external respiratory therapy device; means for determining cardiac cycle phase using the cardiac rhythm monitoring system means, the determining means including means for implantably sensing a parameter indicative of cardiac cycle phase, wherein the determining means determines if the cardiac cycle phase is systole or diastole based on one or more of the parameter and the cardiac pacing information; and means for implantably controlling the airway pressure delivered by the patient-external respiratory therapy device in synchrony with the cardiac cycle phase.
