High-frequency ventilation (HFV) is a type of ventilation that is utilized when conventional ventilation fails. It is a technique where 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] This article is presented for historical purposes as it is no longer used in adults, only in neonates.

A few stated advantages of this technique are:

It reduces the risk of volutrauma and thus helps prevent ventilator-induced lung injury.

It also maintains constant alveolar inflation and thus prevents the inflate-deflate cycle and improves oxygenation.

There are mainly four types of HFV.[...
