Abstract:
1. A respiration information device, comprising: timer circuitry configured to time a plurality of shorter time apertures and a plurality of longer time apertures; a respiration sensor configured to generate a signal indicative of patient respiration; and respiration information circuitry configured to determine, for each aperture of the plurality of shorter time apertures and for each aperture of the plurality of longer time apertures, an estimated value of a respiration characteristic based on the respiration, the respiration information circuitry comprising: measurement circuitry configured to measure the respiration characteristic for each breath cycle of each aperture; and a respiration processor configured to determine the estimated value of the respiration characteristic for each aperture based on the measurement of the respiration characteristic and configured to determine a maximum respiration value from the estimated values determined for the plurality of shorter time apertures and to determine a minimum respiration value from the estimated values determined for the plurality of longer time apertures.
