Figure 4From: Adjusting tidal volume to stress index in an open lung condition optimizes ventilation and prevents overdistension in an experimental model of lung injury and reduced chest wall compliance Lung tissue histopathology. A) (SI-group) and C) (Pplat-group) right ventral sample: mild aggregation of neutrophils and hyaline membrane formation. B) (SI-group) and D) (Pplat-group) right dorsal sample: severe alveolar congestion hemorrhage, neutrophil airspace infiltration and aggregation and vessel wall infiltration, hyaline membrane formation without differences between groups.
