$Mean regional gas fraction (Fgas) for all animals (n = 6) at baseline and after 16 h of mechanical ventilation in six coronal regions of interest (ROIs) of equal height along the ventral–dorsal axis (ROI 1 is the most ventral and ROI 6 the most dorsal). Note that a significant decrease in gas fraction occurred only in dorsal regions (ROIs 5–6). *P < 0.05 (baseline vs. 16 h); #P < 0.01 (vs. previous ROI at baseline); ‡P < 0.05 (vs. previous ROI at 16 h).$
