Figure 2

Static pressure–volume (PV) loops obtained in the eight animals under three lung conditions. The three conditions used were: before lung lavage, after lung lavage, and after lung lavage and additional injurious ventilation (injur vent). Each PV loop was obtained from 0 to 40 cmH2O and back to 0 cmH2O airway pressure by a slow inflation–deflation, interrupted technique. End-expiratory lung volume at 10 cmH2O of positive end-expiratory pressure before a lung recruitment maneuver (LRM) (EELV-10noLRM)(filled circles) and after an LRM (EELV-10LRM) (open circles) agreed well with the volumes found on the inspiratory and expiratory limbs, respectively, of the PV loops.
