Dräger APRV

Airway Pressure Release Ventilation (APRV) is a technique, which allows spontaneous breathing on 2 CPAP levels.

After establishing an adequate level of CPAP, ventilatory support is achieved by adjusting the level of pressure release. In the absence of spontaneous breathing APRV is identical to Pressure Controlled Inverse Ratio Ventilation. APRV is increasingly used in critically ill patients with and without respiratory failure. The proposed clinical applications are in patients where there is a need to minimize the risk of pulmonary barotrauma by reducing the difference between peak and mean airway pressures.
