Learning Objectives:

By the end of this series, listeners should be able to discuss:

1. The physiologic rationale supporting the use of airway pressure release ventilation (APRV) in ARDS.
2. The patient populations most likely to benefit from APRV.
3. Key published evidence that informs our use of APRV in critical care.
4. An expert approach to managing a patient with APRV.
