The high frequency oscillator is used for patients with Respiratory Distress Syndrome and for those patients that have failed conventional mechanical ventilation.

High Frequency Oscillatory Ventilation (HFOV) improves gas exchange by continuous alveolar recruitment with the use of increased mean airway pressures (MAP) and active exhalation. After each patient use the ventilator is to be set up, calibrated and a performance check out performed. The use of the oscillator is to be used on the order of the attending physician.
