WebNov 4, 2024 · The Pre-brief. HFOV uses supraphysiologic frequencies and low tidal volumes. It delivers a constant mean airway pressure without the high peak/plateau pressures and the large change in pressure with each breath of a conventional ventilator (Figure 1). These pressures can be injurious in stiff, noncompliant lungs. WebHigh-frequency oscillatory ventilation simulations demonstrated increasing heterogeneity of regional parenchymal flow with increasing lung size, with decreasing ratio of deadspace to total acinar volume, and with increasing frequency above lung corner frequency and resonant frequency.
