1. A method for controlling an alarm in a medical diagnostic apparatus, the method comprising:

  • measuring a value of a physiological parameter to obtain a measured value;

    determining a dynamic threshold value correlative to the measured value;

    establishing a condition value based at least in part on an integrated product of the extent by which the dynamic threshold value is passed by the measured value over a period of time; and

    triggering an alarm when the condition value exceeds a threshold level.
