Fig. 3

Airway pressures, esophageal pressures and transpulmonary pressures (P L) during conventional mechanical ventilation (CMV) before and after three levels of mean airway pressure (mPaw) during high-frequency oscillatory ventilation (HFO). Airway pressure is plateau pressure (Pplat) during CMV and mPaw during HFO. Esophageal pressure is the inspiratory pressure during CMV and the mean esophageal pressure during HFO. P L is computed by Pplat minus inspiratory esophageal pressure ding CMV and mPaw minus mean esophageal pressure during HFO. *Means < 0.05
