WebHigh-frequency oscillatory ventilation (HFOV) is a form of ventilatory support which delivers very small tidal volumes (1-2 ml per kg) at very high rates (3-15 breaths per second). The … WebApr 30, 2024 · HFOV, another mechanical ventilatory strategy, provides high-frequency, low-amplitude oscillations around a relatively high mean airway pressure. The airway pressure is set to optimize recruitment and the low amplitude is meant to limit ventilator-associated lung injury from volutrauma and atelectrauma.
