Haemodynamics and oxygenation improvement induced by high frequency percussive ventilation in a patient with hypoxia following cardiac surgery: a case report

Table 2 Ventilator setting pre- and post-high frequency percussive ventilation (HFPV)

rate (rate/min)
FiO₂(%)	1	0.6
PEEP (cm H₂O)	14	14
PIP (cm H₂O)	38	34
Inspiratory-expiratory rate	1:1.5	1:1.5

After 12 hours of HFPV, tidal volume (TV) increased from 600 to 750 mL, mean airway pressure (MArP) lowered from 18 to 16 cmH₂O, fractional inspiratory oxygen (FiO₂) from 1 to 0.6%, peak inspiratory pressure (PIP) from 38 to 36 cmH₂O.
