High frequency oscillation HFO is a ventilatory technique which applies tidal volumes less than dead space to the airways at frequencies of 2-50 Hz. Potential benefits have been reported for the clinical use of HFO, especially for premature infants with respiratory distress syndrome. Because of the small tidal volumes, the classical methods for measuring ventilation do not apply during HFO. Several theories have been proposed to explain the mechanism of gas transport but there is presently no general concensus as to the primary mechanism responsible for gas transport during HFO.
