This device is intended for adult and pediatric (excluding neonatal and infant) use.

The ThermiSense Oral/Nasal Thermal AirFlow Sensor with Airflow Pressure Cannulas, Nasal and Oral/Nasal is a thermal resistive thermistor designed to monitor oral/nasal thermal airflow temperature and pressure changes during sleep studies. The ThermiSense is intended for use with a nasal cannula and polysomnography headbox or pressure transducers, such as, BINAPS Nasal Airflow Transducer. This device is intended for adult and pediatric (excluding neonatal and infant) use.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
