HFPPV — High-frequency positive pressure ventilation is rarely used anymore, having been replaced by high-frequency jet, oscillatory and percussive types of ventilation.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. It is a hybrid of conventional mechanical ventilation and high-frequency oscillatory ventilation. It has been used t… WebHigh-frequency ventilation (Passive) The term passive refers to the ventilator's non-forced expiratory system. In a HFV-P scenario, the ventilator uses pressure to apply an inspiratory breath and then returns to atmospheric pressure to allow for a passive expiration. This is seen in High-Frequency Jet Ventilation, sometimes abbreviated HFJV.
WebDuring high-frequency jet ventilation (HFJV), small tidal volumes are delivered at a rate of 60 to 150 cycles per minute from a high-pressure source (5 to 50 psi), with inspiration taking 20% to 40% of each cycle. This is an effective ventilation method that provides adequate gas exchange.
