Intrapulmonary percussive ventilation (IPV) is a form of chest physical therapy administered to the airways by a pneumatic device. Using a breathing circuit called a Phasitron, mini bursts of gas are delivered into the lungs at rates between 100 – 300 breaths per minute (bpm).

How are the lungs protected from barotrauma with the IPV?

IPV was designed to improve mucus clearance and recruit obstructed bronchi and alveoli using a lung protective strategy; it avoids barotrauma caused by over-inflation of preferential airways. By improving mucus clearance, hyperinflation is reduced, and lung mechanics and gas exchange are improved (1).

How long is IPV treatment?
