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

High-frequency oscillatory ventilation (HFOV) is a method of ventilation that theoretically achieves all of the goals of lung protective ventilation (6, 8). HFOV oscillates the lung around a constant mean airway pressure (mPaw) that is higher than that usually applied during conventional ventilation (CV). Although the oscillations may cause significant pressure swings in the endotracheal tube
17/04/2003 · High-frequency jet ventilation and high-frequency positive pressure ventilation are examples of devices employing passive expiration.

High-frequency ventilation (HFV) is the administration of small tidal volumes of 1–3 mL/kg at high frequencies of 100–3000 cpm. 40 Because it is a mode of ventilation based on a marked reduction in tidal volumes and airway pressures, it has the greatest potential for reducing pulmonary barotrauma.

Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation. The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
