High frequency jet ventilation — High frequency jet ventilation (HFJV) refers to HFV delivered using a jet of gas. It is initiated by inserting into the lumen of the endotracheal tube a small (14 to 16 gauge) cannula, which is connected to a specialized ventilator. Jun 01, 2016 · The Conceptual Rationale for Using HFOV. High-frequency oscillatory ventilation (HFOV) is a ventilator support strategy that, in the adult, uses breathing frequencies of 180–900 breaths/min (3–15 Hz) with resulting small V T, often less than anatomic dead space. 7–9 HFOV provides an oscillating pressure/volume waveform superimposed on a constant distending mean airway pressure .
High-frequency ventilation (HFV) as a ventilatory therapy has reached increasing clinical application over the past ten years. The term com-prises several methods. High-frequency jet ventilation must be diffe-rentiated from high-frequency oscillatory ventilation (HFOV or HFO). In this booklet I concentrate on high-frequency oscillatory ventilation. High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value. (>150 (V f) breaths per minute) and very small tidal volumes. High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute lung injury. This is commonly referred to as lung protective MeSH: D006612.

The potential of high-frequency ventilation in humans has been studied since the observation that adequate gas exchange occurred in panting dogs with tidal volumes lower than the anatomic dead space .In the 1970s, groups in Germany and Canada found a system that oscillated gas into and out of an animal's lungs was effective at CO 2 elimination Cited by: 64.
Operating Instructions for High Frequency Oscillatory Ventilation Formulated: 04/03 Effective: Revised: 04/30/03 05/10/18 Operating Instructions for High Frequency Oscillatory Ventilation (HFOV) Purpose To provide guidelines for the initiation of therapy and troubleshooting for the Sensormedics 3100A High Frequency Oscillatory Ventilator. High frequency jet ventilation may help reduce chronic lung disease in preterm babies but adverse effects are unclear. Lung disease is a major cause of death in very low birth weight babies. Chronic lung disease (CLD) following mechanical ventilation for babies with breathing difficulties is also common. It is possible that the low gas exchange in newborns during breathing may help cause.
