1. A method for detecting venous pulsation, comprising:

  • receiving one or more signals from a sensor, the signals corresponding to absorption of light in a patient'"'"'s tissue;

    determining a characteristic of the sensor;

    performing a venous pulsation detection algorithm on the one or more signals, wherein the venous pulsation detection algorithm is performed at a sensitivity level based on the characteristic of the sensor; and

    determining whether venous pulsation is present based on the performance of the venous pulsation detection algorithm.
