1. A method of developing a respiration pacing signal in an implanted patient with impaired breathing, the method comprising:

  • detecting respiration activity in the implanted patient and developing a corresponding respiration signal;

    detecting movement of the implanted patient and developing a corresponding movement signal;

    using a pacing processor to follow a series of computer instructions fixed on a non-transitory computer readable medium to receive the respiration signal and the movement signal and generate a respiration pacing signal synchronized with the detected respiration activity; and

    delivering the respiration pacing signal from the pacing processor with a stimulating electrode to respiration neural tissue of the implanted patient to promote breathing of the implanted patient;

    wherein using the pacing processor includes using a plurality of respiration sensing modes that reflect activity of the movement signal over time to optimize system power consumption over time,wherein the plurality of respiration sensing modes includes;

    i. an active respiration mode when the movement signal is either actively changing or remains unchanged for a period less than a reduced activity period, wherein the respiration signal is measured continuously, andii. a plurality of reduced activity respiration modes when the movement signal remains unchanged for the reduced activity period, wherein the respiration signal is measured only during a limited respiration sampling period.
