What advantage does APRV offer when used correctly?

• A. Increased respiratory rate
• B. Utilization of lung protection strategies
• C. Decreased oxygenation
• D. Elimination of assisted ventilation

Answer: (B)

APRV, or Airway Pressure Release Ventilation, is designed to allow for optimal lung recruitment and is particularly effective in protecting against ventilator-induced lung injury. One of its main advantages when implemented correctly is that it facilitates lung protection strategies. In APRV, the patient is exposed to higher levels of positive airway pressure during the inspiratory phase, which aids in recruiting collapsed or poorly ventilated alveoli. This recruitment helps improve gas exchange and reduces the need for high tidal volumes, supporting lung mechanics while minimizing barotrauma and volutrauma. The strategy also allows for spontaneous breathing during the release phase, further enhancing patient comfort and promoting pulmonary function without excessive tidal volume. This mode is valuable for managing acute respiratory distress syndrome (ARDS) or similar conditions where lung protection is crucial. The emphasis on lung recruitment and protection directly contributes to more efficient ventilation and lower risks of injury, making advanced strategies like APRV a vital option for impaired lung function.
