Airflow sensors are used during sleep studies to measure and monitor the flow of breathing to help clinicians detect sleep-disordered breathing. They use various technologies, such as pressure transducers and polyvinylidene fluoride, to detect inhalation and exhalation. Airflow sensors are available in disposable and reusable options. Sleep Review‘s airflow sensor guide is a comparison of the major medical sensors available on the sleep market.

Description:The ValueLine Pressure Sensor has a small footprint and plugs into your AC headbox using two pairs of touchproof 1.5 mm safety connectors. The internal piezo pressure sensor does not require batteries.
Sleepmate Airflow Pressure Transducers are a small single channel sensor. The reusable transducer couple with disposable cannulae with or without filters.  
Dymedix pediatric airflow sensors provide enhanced sensitivity through PVDF technology. They are designed for use with Dymedix iFM, a specialized airflow interface cable that boosts and filters airflow waveforms allowing for more accurate and detailed sensing of airflow activity from neonate and infant patients.Dymedix TriplePlay Airflow Sensors detect three types of sleep-disordered breathing events with only one sensor: apnea, hypopnea, and snore. The TriplePlay PVDF technology responds to changes in both pressure and temperature resulting in accurate detection of apnea, hypopnea, UARS, and snore, all with one sensor. 

The SleepSense ThermoCan monitors oral/nasal thermal airflow and nasal pressure simultaneously. Disposable ThermoCan Cannulas are designed with a built-in thermal airflow sensor. ThermoCan Interface Cables have 2 gold pins that insert into the sides of ThermoCan Cannulas at the nares, transmitting the thermal airflow signal to the system and replacing the need for thermistor
