HFJV vs HFOV

Summary This conversation discusses high frequency ventilation, specifically comparing jet ventilation and oscillatory ventilation. The primary reasons for using high frequency ventilation are to prevent lung injury and improve gas exchange. Lung injury can be caused by barotrauma, volume trauma, and adelectrauma. Jet ventilation involves using a jet ventilator and a conventional ventilator, while oscillatory ventilation uses a single machine. Adjustments for ventilation in jet ventilation are primarily made by changing the peak inspiratory pressure (PIP), while in oscillatory ventilation, the amplitude is the primary adjustment. Oxygenation is controlled by adjusting FiO2 and PIP in jet ventilation, and by adjusting mean airway pressure (MAP) and FiO2 in oscillatory ventilation.
