The Extent of Ventilator-Induced Lung Injury in Mice Partly Depends on Duration of Mechanical Ventilation

Figure 7

Histopathology. Lung sections were stained with hematoxylin eosin (H&E) to analyze lung histopathology (magnification 100x). Total histopathology score was determined by the sum of the score for 4 pathologic parameters: (a) edema, (b) hemorrhage, (c) interstitial cell infiltration, and (d) hyaline membranes. NVC = nonventilated controls; LVT, HVT = LVT/PEEP or HVT/ZEEP ventilator settings; 5 h, 12 h = 5 or 12 hours of ventilation.
