Different Tidal Volumes May Jeopardize Pulmonary Redox and Inflammatory Status in Healthy Rats Undergoing Mechanical Ventilation

Histological images of lungs pertaining to all experimental groups (upper four panels). Stereological analyses of lung sections (lower two plots). CG: control group; MVG4, MVG8, and MVG12: mechanical ventilation groups ventilated with 4 mL/kg, 8 mL/kg, and 12 mL/kg, respectively. Volume density (%Vv) of the alveolar airspace (a) and alveolar septa (b). Photomicrographs of lung sections stained with hematoxylin and eosin.  μm, 400x magnification. Data are expressed as median, 25% and 75% percentiles; whiskers encompass upper and lower limits and were analyzed by Kruskal-Wallis ANOVA followed by Dunn’s posttest. animals/group. Significantly different groups are indicated by horizontal square brackets and values.
