Airway Pressure Release Ventilation: Theory and …

Airway Pressure Release ventilation (APRV) is a relatively new mode ofventilation, that only becamecommercially available in the UnitedStates in the mid-1990s. Airway pressurerelease ventilation produces tidalventilation using a method that differsfrom any other mode. It uses a Release ofairway Pressure from an elevatedbaseline to simulate expiration. Theelevated baseline facilitates oxygenation,and the timed releases aid in carbondioxide of APRV include lowerairway pressures, lower minuteventilation, minimal adverse effects oncardio-circulatory function, ability tospontaneously breathe throughout theentire ventilatory cycle, decreasedsedation use, and near elimination ofneuromuscular blockade. Airway pressurerelease ventilation is consistent with lungprotection strategies that strive to limitlung injury associated with mechanicalventilation. Future research will probablysupport the use of APRV as the primarymode of choice for patients with acutelung injury.
