Pulmonary Function Testing

In pulmonary function testing, the opportunity for cross-contamination between patients and equipment is a known concern. 

Despite efforts to control cross-contamination by exchanging mouthpieces and tubing between patients, there is the possibility of contamination from aerosolized droplets into the irreplaceable components of the pulmonary function testing device.

Our Pro-Tec® Filter for Pulmonary Function Testing is a barrier filter designed to reduce the risk of cross-contamination due to saliva microdroplets or particulate in exhaled gas. It prevents the collection of aerosolized droplets on pneumotachs, valves, tubing, and reservoirs, while creating minimal resistance. Completely disposable, this device is provided ready to use and may be used as a mouthpiece.
