LRM, lung recruitment maneuver; PEEP, positive end-expiratory pressure; EELV, end-expiratory lung volume; Crs, compliance of the respiratory system; PaCO₂, partial pressure of arterial CO₂; PaO₂, partial pressure of arterial oxygen.

The three lung conditions: before lung lavage, after lung lavage and after lung lavage and additional injurious mechanical ventilation

Results are presented as medians and 25th and 75th centiles.

^aP < 0.05, before LRM compared with after LRM in the three lung conditions; ^bP < 0.05, before lung lavage compared with after lung lavage or after lung lavage and additional injurious ventilation before the LRM.
