Question

Quizplus · Accepted Answer

Airway pressure-release ventilation (APRV) is a mode of mechanical ventilation that is designed to optimize ventilation by recruiting alveolar units while minimizing ventilator-induced barotrauma in patients with ARDS. Unlike traditional ventilation modes, APRV utilizes higher levels of continuous airway pressure to recruit collapsed alveoli, while also allowing for spontaneous breathing at lower airway pressure levels. This approach has been shown to improve oxygenation and lung compliance while reducing the risk of complications such as barotrauma and ventilator-associated pneumonia. In contrast, inverse-ratio ventilation and high-frequency ventilation are also used in ARDS but are not necessarily designed to minimize barotrauma. Intermittent mandatory ventilation is a mode that is typically used in a variety of situations but is not specific to ARDS.
