High-frequency oscillatory ventilation: A narrative review - PMC
High-frequency oscillatory ventilation (HFOV) is a lung-protective strategy that can be utilized in the full spectrum of patient populations ranging from neonatal to adults with acute lung injury. HFOV is often utilized as a rescue strategy when conventional mechanical ventilation (CV) …

The Physiological Basis of High-Frequency Oscillatory Ventilation …
This article aims to review the physiologic rationale for the use of HFOV in patients with acute respiratory failure, summarize relevant bench and animal models, and discuss the potential use of HFOV as a primary and rescue mode in adults and children with severe respiratory failure.

High-frequency oscillatory ventilation (HFOV) is a form of ventilatory support that delivers extremely small tidal volumes (V Ts) at very high rates and maintains a relatively constant and higher mean airway pressure (mPaw) than mechanical ventilation.
Numerical study of high frequency oscillatory air flow and …
(a) Front view of the CT-based airways (LMB, left main bronchus; RMB, right main bronchus). Solid, dot-dashed, and dashed boxes indicate the locations of selected bifurcations between G0-1, G2-3, and G3-4 (see Figs. 8-11), respectively.A and B denote particle released locations in HFOV and HFNR, respectively, for stretch rate analysis.
nitial status as a novel ventilatory tool, to become a routine ventilatory strategy. High-frequency ventilation comprises several different modalities including high-frequency positive pressure ventilation, high frequency flow interruption, hi.

Jul 5, 2024 · As ARDS is a heterogeneous lung disease from differing causes, there may be some patient subgroups that might be helped (e.g. patients with homogeneous, recruitable lung) while others are harmed — but we don’t know if this is true! — HFOV strategy had high mean airway pressures – would a lower mean airway pressure strategy make a difference?
High-Frequency Oscillatory Ventilation (HFOV) is a mode of ventilation which has been in clinical use for over thirty years. In many hospitals around the world, HFOV is not only a common rescue strategy but is increasingly an established as first-intention …
