Intrapulmonary Percussive Ventilation (IPV)

Intrapulmonary percussive ventilation is one method of helping patients clear lung secretions. It relies on a machine that delivers multiple small bursts of oxygen through endotracheal or tracheostomy tubing. These bursts of air beat on the alveolar secretions like a drum. This rhythmic beating helps mucous, pus, and fluid in the lung spaces mobilize so that it can be suctioned or coughed out. The overall effect is an improvement in pulmonary toilet.



Intrapulmonary percussive ventilation is one way of helping ventilated patients break up lung secretions and re-inflate collapsed alveoli.
