    摘要： A method of determining a respiration parameter in a medical device in which pressure signals are sensed to generate corresponding sample points, and a breath detection threshold is continuously adjusted in response to the generated sample points to generate a current adjusted breath detection threshold. A current generated sample point is compared to the current adjusted breath detection threshold, and the continuous adjusting of the breath detection threshold is suspended and the breath detection threshold is equal to the most current adjusted breath detection threshold generated prior to the suspending in response to the comparing. A next sample point, generated subsequent to the suspending, is compared to the set breath detection threshold, and the respiration parameter is determined in response to the comparing of a next sample point to the set breath detection threshold.

    摘要： Systems and methods for improving hemodynamic data interpretation by accounting for the effects of patient posture is disclosed. In certain embodiments, a posture signal is acquired and used to categorize hemodynamic data according to posture to facilitate distinguishing posture-related changes in acquired hemodynamic data from those due to pathophysiologic changes. Posture information may be used to normalize data acquired in various postures to facilitate interpretation of such data. Baseline measurements of hemodynamic data acquired in various postures may also be used to subsequently detect changes in patient posture without the need for an implanted posture sensor.
