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

Cell infiltration. (a) Total cell counts were measured in bronchoalveolar lavage fluid (BALF). ((b)-(c)) Differential cell counts were performed on BALF cytospin preparations to determine neutrophil and macrophage infiltration. Data are presented as scatter plot (median) of 6–8 mice per group (triangle = NVC; circle = LVT; square = HVT). *Illustrates primary statistical analysis (* , ** ); #illustrates secondary statistical analysis (## ). NVC = nonventilated controls; LVT, HVT = LVT/PEEP or HVT/ZEEP ventilator settings; 5 h, 12 h = 5 or 12 hours of ventilation.
