High-frequency ventilation

High-frequency ventilation
MeSHD006612

High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value[1] (>150 (Vf) breaths per minute) and very small tidal volumes.[2][3] High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute lung injury.[2] This is commonly referred to as lung protective ventilation.[4] There are different types of high-frequency ventilation.[2] Each type has its own unique advantages and disadvantages. The types of HFV are characterized by the delivery system and the type of exhalation phase.

High-frequency ventilation may be used alone, or in combination with conventional mechanical ventilation. In general, those devices that need conventional mechanical ventilation do not produce the same lung protective effects as those that can operate without tidal breathing. Specifications and capabilities will vary depending on the device manufacturer.
