In previous posts, we discussed a number of technical advantages that polyvinylidene fluoride (PVDF) based sensors are capable of providing. With airflow detection, they are extremely responsive, very linear, and more stable compared to other traditional flow and pressure sensors. With respiratory effort, they are also equally responsive, linear and eliminate phase and polarity shifts compared to standard piezo crystal and RIP belts. This results in superior waveforms that ultimately produce higher quality recordings that are easier to score and interpret.
However, there are additional advantages of using PVDF-based sensors. Our airflow sensors can be used with 5 different Airflow Filtration Module interface cables that provide the user with a variety of waveform options and combinations. This includes generating up to 3 signals from a single sensor; one for scoring apnea events, one for scoring hypopnea events, and a final output for snoring. PVDF-based sensors also eliminate the need for nasal cannulas, a distinct advantage to the patient in terms of comfort which encourages a more restful night and better data to interpret.
All our PVDF-based sensors are made in America and come with an unmatched 1-year warranty, which is more than most other sensors in the industry. They are accepted by the AASM and available in adult and pediatric sizes in both reusable and disposable versions.
