From: New and conventional strategies for lung recruitment in acute respiratory distress syndrome
Pulmonary perfusion maps of the left lung in one animal with acute lung injury induced by lavage. Left panel: Perfusion map after induction of injury and mechanical ventilation according to the ARDS Network protocol. Right panel: Perfusion map after 6 h of mechanical ventilation according to the ARDS Network protocol, but using variable tidal volumes. Note the increase in perfusion in the more dependent basal-dorsal zones (ellipses), suggesting alveolar recruitment through variable ventilation. Blue voxels represents lowest and red voxels, highest relative pulmonary blood flow. Adapted from [41].
