In this podcast episode, Dr. Rory Spiegel discusses the challenges of breathing, particularly in cases of wet, heavy lungs and increased dead space. The focus shifts to APRV (Airway Pressure Release Ventilation) as a mode of ventilation and its benefits in returning patients to Functional Residual Capacity (FRC). Dr. Spiegel emphasizes the importance of understanding FRC in the context of ARDS (Acute Respiratory Distress Syndrome) and dispels myths surrounding APRV. He delves into the physiological aspects, including the viscoelastic nature of the lung and the impact on dead space. The episode concludes by highlighting the practical goal of maintaining patients at FRC for improved outcomes, touching on aspects like heart function, sedation, and reduced barotrauma.
