Figure 2From: Non-lobar atelectasis generates inflammation and structural alveolar injury in the surrounding healthy tissue during mechanical ventilationVolume/surface (V/S) ratio grid. Representative images (200×) from histological preparation of an animal of tidal volume = 20 ml/kg and positive end-expiratory pressure = 0 cmH2O group. The grid used for calculation of the V/S ratio is superimposed on the fields. A Corresponds to peri-atelectasis, and B corresponds to control lung region.Back to article page
