What mode of mechanical ventilation is designed to optimize ventilation by reducing alveolar collapse while using small tidal volumes in patients with ARDS?

a. Inverse ratio ventilation
b. High-frequency ventilation (HFV)
c. Intermittent mandatory ventilation
d. Airway pressure-release ventilation

ANS: B
HFV was designed to simultaneously maintain adequate ventilation and reduce alveolar collapse through ventilation with high expiratory lung volumes and rapid (up to 300 breaths/min), small tidal volumes (3 to −5 ml/kg).
