1. A patient monitor receiving a noninvasive optical sensor signal and conditionally outputting an indication of a pulse occurrence, the monitor comprising:

  • an input signal from said sensor; and

    one or more signal processors configured to;

    present a caregiver with user-selectable configuration parameters that customize a trigger decision when distortion occurs in said input signal thereby providing said caregiver expected monitor behavior during at least signal distortion;

    determine a measure of distortion in said input signal; and

    determine the trigger decision based on the measured distortion and said user-selectable configuration parameters;

    said trigger decision comprising one of providing an indication of pulse occurrences even when the measured signal distortion is high, or providing no output when the signal distortion is high.
