Systems and methods for determining respiration metrics
First Claim
1. A method, comprising:
- generating a signal indicative of respiration;
determining, for each aperture of a plurality of shorter time apertures and for each aperture of a plurality of longer time apertures, an estimated characteristic of the respiration based on the respiration signal; and
determining one or more respiration metrics using one or both of the estimated respiration characteristics of the plurality of shorter time apertures and the estimated respiration characteristics of the plurality of longer time apertures.

Abstract
Systems, devices and methods provide for acquiring respiration information. A respiration information device includes timer circuitry to time a plurality of shorter time apertures and a plurality of longer time apertures. A respiration sensor, which may be implemented as a transthoracic impedance sensor, is configured to generate a signal indicative of patient respiration. For each aperture of the plurality of shorter time apertures and for each aperture of the plurality of longer time apertures, an estimated characteristic of the respiration is determined. Respiration metrics are developed using one or both of the estimated respiration characteristics of the shorter time apertures and the estimated respiration characteristics of the longer time apertures.
