All the patients was ventilated in controled ventilation with 6 ml/kg (PBW) of tidal volume (Vt) and a respiratory rate (RR) above 25/min.
During high-frequency oscillatory ventilation, each animal was ventilated with bias flows of 10, 20, 30, and 40 L/min in random sequence.
Following the first RM, the patient was ventilated with the initial ventilator settings.
A lung model (TTL, Michigan Instruments) was ventilated using a PB840 ventilator (Puritan-Bennett) via an 8 mm ETT.
The patient was ventilated using high-frequency oscillatory ventilation in combination with nitric oxide (NO), but the oxygenation did not improve significantly.
After admission to the ICU each patient was ventilated with an 8400 STi ventilator (Bird Corp., Palm Springs, CA, USA).
From the beginning of the transport the pig was ventilated with a portable medical ventilator (Oxylog, Dräger, Germany).
