Acceleration sensors for recording of triggered respiratory signals in neurostimulators
First Claim
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.

Abstract
A method of developing a respiration pacing signal includes detecting respiration and movement activity in an implanted patient and developing corresponding respiration and movement signals. A respiration pacing signal is synchronized with the detected respiration activity and delivered to respiration neural tissue of the implanted patient to promote breathing of the implanted patient. A plurality of respiration sensing modes are used that reflect activity of the movement signal over time to optimize system power consumption over time, including: i. an active respiration mode when the movement signal is either actively changing or remains unchanged for a brief period less than some reduced activity period, wherein the respiration signal is measured continuously, and ii. a plurality of reduced activity respiration modes when the movement signal has remained unchanged for the reduced activity period, wherein the respiration signal is measured only during a limited respiration sampling period.
