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. | ||||||
