Fig. 3From: Comparison between effects of pressure support and pressure-controlled ventilation on lung and diaphragmatic damage in experimental emphysemaLung morphometry. a Mean linear intercept (Lm), fraction area of hyperinflated and collapsed alveoli. b Representative photomicrographs of lung parenchyma stained with hematoxylin–eosin. Note alveolar space enlargement in the emphysema group (arrows). PCV pressure-controlled ventilation, PSV pressure support ventilation. Boxes show the interquartile (25–75 %) range, whiskers encompass the range (minimum–maximum), and horizontal lines represent the median in six animals/group. *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
