Thermistor Flow Sensor Alice 5

Comprised of three or four heat sensitive elements, respiration flow sensors are placed under the patient’s nostrils and produce a signal that is directly proportional to the temperature changes of air inhaled and exhaled during respiration.  SleepSense thermal airflow sensors generate a small analog electrical voltage that provides a clear, reliable indication of respiration airflow.  These sensors should be connected to the system’s thermal-flow input.  The SleepSense 1471 sensor is designed specifically for use with the Alice 5 system.
