Overview of APRV and Its Application

APRV, or Airway Pressure Release Ventilation, is discussed as a mode of ventilation that provides continuous positive airway pressure with periodic releases. It is particularly useful for patients with significantly reduced lung volumes, aiming to restore functional residual capacity (FRC). This mode is suggested for patients who may experience issues such as obesity hypoventilation or lung injury, as it allows for less obstructive ventilation compared to conventional modes. The clinical case of a 60-year-old male with hypoxia and obesity demonstrates a scenario where APRV would be beneficial.
