SYSTEM AND METHOD FOR DETECTION OF VENOUS PULSATION

摘要

In accordance with an embodiment of the present technique, there is provided methods and systems for detecting the presence of venous pulsation by adjusting the sensitivity of a detection algorithm based on a sensor characteristic and/or notifying a caregiver of the presence of venous pulsation by ceasing display of physiological parameters. An exemplary embodiment includes receiving one or more signals from a sensor, the one or more signals corresponding to absorption of light in a patient's tissue; calculating one or more physiological parameters of the patient based on the one or more signals; displaying the patient's physiological parameters; enabling detection of venous pulsation (148) with variable sensitivity based on a location of the sensor; and suspending or terminating the display of the one or more of the patient's physiological parameters when venous pulsation is detected (154).
