HFPPV — High-frequency positive pressure ventilation is rarely used anymore, having been replaced by high-frequency jet, oscillatory and percussive types of ventilation. HFPPV is delivered through the endotracheal tube using a conventional ventilator whose frequency is set near its upper limits. HFPV began to be used in selected centres in the 1980s.
