1. A method of determining a respiration parameter in a medical device, comprising:

  • sensing pressure signals to generate corresponding sample points;

    continuously adjusting a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold;

    comparing a current generated sample point to the current adjusted breath detection threshold;

    suspending the continuous adjusting of the breath detection threshold and setting the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending;

    comparing a next sample point, generated subsequent to the suspending, to the set breath detection threshold; and

    determining the respiration parameter in response to the comparing of a next sample point to the set breath detection threshold.
