Thoracic tomography of two different models of acute lung injury/acute respiratory distress syndrome (ARDS). (a) Computed tomography (CT) scan of pigs after saline lung lavage before and after recruitment maneuvers with 45 cmH₂O of pressure, maintaining a positive end-expiratory pressure (PEEP) of 10 cmH₂O, showing some redistribution of ventilation [1]. (b) CT scan of acute respiratory distress syndrome patients before and after a recruitment maneuver with 60 cmH₂O maximal inspiratory pressure maintaining PEEP values of 20 and 25 cmH₂O.
