8/04/2005 · High-frequency oscillatory ventilation (HFOV) is, from a theoretical point of view, an ideal method of ventilation to minimize ventilator-associated lung injury. HFOV avoids high peak inspiratory pressures, thus preventing end-inspiratory overdistension, and it avoids repetitive recruitment and de-recruitment of the unstable lung alveoli, thus preventing end-expiratory collapse [ 1 – 3 ].
High frequency oscillatory ventilation (HFOV) offers an alternative means of ventilation for such cases. It maintains a constant distending pressure for the alveoli and optimal lung volumes while limiting
