METHOD FOR MONITORING SENSOR DEGRADATION, PATIENT MONITOR, PATIENT MONITOR SYSTEM, PHYSIOLOGICAL SENSOR, AND COMPUTER PROGRAM PRODUCT FOR A PATIENT MONITOR
A method for monitoring degradation a physiological sensor connected to a patient monitor is disclosed. A patient monitor, a patient monitor system, a physiological sensor, and a computer program product are also disclosed. In order to get an early warning of an imminent breakage or wear out of a physiological sensor and to increase the life time of the sensor without compromising patient safety, history data is collected for at least one sensor feature parameter into a predetermined memory location, wherein the collected history data is indicative of past characteristics of the sensor. The history data is retrieved from the predetermined memory location when the physiological sensor is connected to a patient monitor and a degradation measure indicative of the degree of degradation of the physiological sensor is determined for the physiological sensor based on the history data.
