High-frequency ventilation (HFV) is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value [1] (>150 (V f) breaths per minute) and very small tidal volumes.

高频通气法（high frequency ventilation，HFV）采用明显高于生理呼吸次数的频率，以极低的潮气量进行通气。 该通气技术的原理虽有悖于传统的呼吸生理概念，但仍可维持有效的气体交换。

2022年9月29日 · High-frequency ventilation (HFV) is a type of ventilation utilized when conventional ventilation fails. In this technique, the set respiratory rate greatly exceeds the normal breathing rate. In this rescue strategy, the tidal volume delivered is significantly less and can also be less than dead space ventilation.[1]

- To convert to CMV, use a MAP 3-4 cm less than the MAP on HFV How do I know it’s working? - Patient SpO2 in the first 30-60 minutes of initiation can change dynamically

2025年2月19日 · High-frequency ventilation (HFV) is a form of mechanical ventilation that combines very high respiratory rates (>60 breaths per minute) with tidal volumes that are smaller than the volume of anatomic dead space [1].

High-frequency oscillatory ventilation (HFOV) is a rescue maneuver for failed conventional mechanical ventilation. It utilizes the Taylor augmented dispersion of gases through a simple circuit in which bias flow delivers small tidal volumes for patients with acute respiratory distress syndrome (ARDS) and other medical conditions [1 – 4].

以低平均气道压和小潮气量为主要特征的高频震荡通气（HFOV），自出现以来备受医务、科研人员的关注。 本文就 HFOV 通气技术方面的研究现状与发展趋势进行了分析和展望，重点介绍与分析了有关 HFOV 的通气模型、通气机制和通气模式方面的研究现状。 并藉此提出，在未来一段时期内，对 HFOV 通气技术的研究将主要集中在三个方面：建立多级、高阶、非线性的黏性阻力、惯性阻力和顺应性（RIC）通气模型；更为充分地揭示 HFOV 之所以能够有效通气的机制；研究 …

High-frequency ventilation (HFV) has progressed over the last thirty years from its initial 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,

High-frequency jet ventilation (HFJV) delivers short pulses of pressurized gas directly into the upper airway via a special endotracheal tube containing a HFJV injector port. In contrast to HFOV, exhalation is passive, resulting in somewhat lower optimal operating frequencies.
