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 1450S sensor can be used with the 1450B Interface Box (safety DIN connector) and connected to the system’s thermal-flow input or AC channel on the recorder.
The SleepSense 1450S sensor can also be used with any system that accepts thermistors with a key connector.
