Abstract
A temperature control system for an electrically heated cutaneous gas sensor. A closed loop temperature control circuit varies the current through the heating element, in accordance with the sensed temperature of the sensor, to maintain the sensor at a temperature approximately equal to that set by a temperature setpoint signal. As the sensor is first placed on a patient, the magnitude of the temperature setpoint signal is increased above its normal value, for a predetermined time, in order to decrease the time delay between the time that the sensor is placed on the patient and the time that the sensor begins to provide usable data.
