The SleepSense Thermistor Flow Sensor (# 1465) was designed specifically for the PDX system.

Warranty: 6 Months – Free of Defects in Materials and Quality Workmanship.

Comprised of three heat-sensitive elements, the SleepSense respiration flow sensor is placed under the patient’s nostrils and produces a signal that is directly proportional to the temperature changes of air inhaled and exhaled during respiration. The sensor generates a small analog electrical voltage that provides a clear, reliable indication of respiration airflow.

This sensor should be connected to the system’s thermal flow input. The sensor’s sleek design provides patient comfort and consistent signals throughout the night.

Compatibility: The SleepSense Thermistor Flow Sensor is completely compatible with the Philips Respironics PDX unit.

NOTE: SleepSense items are for professional use only, and are for sale by or on the order of a physician only.
