1. A respiration implant system for an implanted patient with impaired breathing, the system comprising:
- a respiration sensor configured to detect respiration activity in the implanted patient and develop a corresponding respiration signal;
a movement sensor configured to detect movement of the implanted patient and develop a corresponding movement signal;
a pacing processor configured to receive the respiration signal from the respiration sensor and the movement signal from the movement sensor to generate a respiration pacing signal synchronized with the detected respiration activity; and
a stimulating electrode configured to deliver the respiration pacing signal from the pacing processor to respiration neural tissue of the implanted patient to promote breathing of the implanted patient;
wherein the pacing processor is configured to optimize system power consumption over time by using a plurality of respiration sensing modes that reflect activity of the movement signal over time, andwherein the plurality of respiration sensing modes includes;
a. an active respiration mode during which the movement signal is either actively changing or remains unchanged for a brief period less than some reduced activity period, and during which the respiration signal is measured continuously, andb. a reduced activity respiration mode during which the movement signal has remained unchanged for the reduced activity period and in which the respiration signal is measured only during a limited respiration sampling period.

Abstract
A respiration implant system includes a pacing processor configured to receive a respiration signal and a movement signal to generate a respiration pacing signal that is synchronized with the detected respiration activity. The pacing processor is configured to optimize system power consumption over time by using multiple respiration sensing modes that reflect activity of the movement signal over time.
