high-frequency oscillatory ventilation

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

high-frequency oscillatory ventilation (HFOV),

a mechanical ventilation system that supplies a continuous distending pressure to the respiratory tract and, in addition, generates rapidly oscillating ventilatory cycles at small tidal volume.

high-frequency oscillatory ventilation

Abbreviation: HFOV
Pulmonary ventilation with multiple rapid breaths given at small tidal volumes. It limits the stretching and collapse of the alveoli that occur in conventional mechanical ventilation.

In addition to lung-protective ventilation, the modalities currently being tested in the hope of better oxygenation and lower mortality in patients with acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) include recruitment manoeuvres (RM), prone positioning, various levels of positive end-expiratory pressure (PEEP) and high-frequency oscillatory ventilation (1-5).
