High-Frequency Oscillatory Ventilation in Adults With ARDS Past, Present, and Future Michael C. Sklar, MD; Eddy Fan, MD, PhD; and Ewan C. Goligher, MD, PhD High-frequency oscillatory ventilation (HFOV) is a unique mode of mechanical ventilation that uses nonconventional gas exchange mechanisms to deliver ventilation at very low tidal volumes. The series High Frequency Oscillatory Ventilators (HFOV) are proven for intervening in treating respiratory failure in neonates and ARDS in pediatric and adult patients.
Jun 01, · High-frequency oscillatory ventilation (HFOV) is a ventilator support strategy that, in the adult, uses breathing frequencies of – 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 (̄P aw). High-frequency oscillatory ventilation (HFOV) is a form of ventilatory support which delivers very small tidal volumes ( ml per kg) at very high rates ( breaths per second). The major indication for HFOV is for patients with severe acute respiratory distress syndrome (ARDS) whose lungs cannot tolerate high tidal distending pressure.
Jul 03, · HFOV was initially used in adult patients with respiratory failure as a rescue therapy in refractory hypoxemia. A large retrospective study from three academic ICUs described the use of HFOV for refractory hypoxemia in patients. 43Cited by: Oct 11, · Used for neonatal, pediatric, and adult forms of respiratory failure, HFOV differs from conventional mechanical ventilation by maintaining open lung volume through a constant mean airway pressure to achieve effective oxygenation, while oscillation removes CO 2.
