Disposable ThermoCan Cannulas are uniquely designed with a built-in thermistor making it easier and more cost effective to monitor thermal and pressure flow at the same time. Reusable ThermoCan Interface Cables easily insert into the sides of ThermoCan Cannulas, transmitting the thermal airflow signal to the PSG system and replacing the need for expensive thermistors. 2ft ThermoCan Cannulas are perfect for HST devices or systems utlizing a patient unit, requiring a shorter thermal+pressure combination solution.
