1. An apparatus for determining a respiration parameter in a medical device, comprising:

  • a pressure sensor to sense pressure signals;

    a signal processor coupled to the pressure sensor to receive the sensed pressure signals and generate corresponding sample points; and

    a microprocessor to continuously adjust a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold, compare a current generated sample point to the current adjusted breath detection threshold, suspend the continuous adjusting of the breath detection threshold and set the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending, and determine the respiration parameter in response to a comparing of a next generated sample point to the set breath detection threshold.
