The term passive refers back to the ventilator’s non-pressured expiratory system. In a HFV-P situation, the ventilator uses stress to apply an inspiratory breath and then returns to atmospheric stress to allow for a passive expiration. This is seen in High-Frequency Jet Ventilation, from time to time abbreviated HFJV. Also labeled below High Frequency Ventilation is High Frequency Percussive Ventilation, sometimes abbreviated HFPV. With HFPV it makes use of an open circuit to supply its subtidal volumes with the aid of way of the patient interface called the Phasitron.
