High-frequency ventilation in adults - UpToDate
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 ventilation - Wikipedia
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.
High Frequency Ventilation - StatPearls - NCBI Bookshelf
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 - Adequate “jiggling” / “wobbling” / “chest wiggle” = patient is being ventilated
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) …
High Frequency Ventilation. What Is the Best Choice?
2012年2月7日 · High frequency ventilation (HFV) is a ventilatory strategy that utilizes 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.

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 Oscillation Ventilation - LITFL
2024年7月5日 · High Frequency Oscillation Ventilation (HFOV) is an unconventional form of mechanical ventilation that maintains lung recruitment, avoids overdistention, and does not rely on bulk flow for oxygenation and ventilation. DESCRIPTION. MECHANISM OF GAS EXCHANGE.
The Physiological Basis of High-Frequency Oscillatory Ventilation …
High-frequency oscillatory ventilation (HFOV) is a type of invasive mechanical ventilation that employs supra-physiologic respiratory rates and low tidal volumes (V T) that approximate the anatomic deadspace. During HFOV, mean airway pressure is set and gas is then displaced towards and away from the patient through a piston.
