摘要：
Described herein are methods and apparatus monitoring a patient. In one example, a sensor that is configured to detect physiological changes in a patient is driven at a first current level and a subsequent sensor voltage is measured. Thereafter the current is varied to a second current level, and a next sensor voltage is measured. A next sensor voltage is projected based on the sensor voltage and the subsequent sensor voltage, and a third current level is identified that could produce the next sensor voltage. The third current level is compared to a threshold, and an alarm is produced in response thereto. The apparatus further includes elements in the sensor that facilitate the method.
