System and method for detection of venous pulsation

A system, comprising:

• a sensor configured to acquire one or more signals from a patient, wherein the one or more signals correspond to absorption of light in a patient's tissue;
• and
• a patient monitor comprising a display and a processor, wherein the processor is configured to:
• receive the one or more signals from the sensor;
• determine a characteristic of the sensor;
• calculate one or more physiological parameters of the patient based on the one or more signals;
• determine if venous pulsation is present based on the one or more signals by performing a venous pulsation detection algorithm at a sensitivity level based on the characteristic of the sensor;
• and
• cause the suspension or termination of display of the one or more physiological parameters on the display based on detection of venous pulsation.

A system, comprising:

• a patient monitor comprising a processor configured to:
• receive a first signal from a sensor indicating sensor type;
• receive a second signal from the sensor, wherein the second signal corresponds to absorption of light in a patient's tissue;
• enable or disable a function configured to detect venous pulsation based on the sensor type and determine whether the venous pulsation is present when the function is enabled;
• and
• subsequent to enabling or disabling the function, calculate one or more physiological parameters based on the second signal corresponding to the absorption of light in the patient's tissue.
