Diaphragm muscle injury score (MIS), cross-sectional muscle fiber diameter and H & E stained cross-sections of diaphragm. (Clear bars are Nitrox breathing animals and dashed bars are Heliox breathing). (a) Muscle injury Score comparing nitrox to heliox sections. Muscle Injury was attenuated in heliox breathing pigs compared to nitrox group (* P < 0.01). (b) Muscle fiber diameter was similar between both groups (P > 0.05). (c & d) H&E stained cross-sections of diaphragm (magnification 400x) obtained from one newborn pig in each group. (c) Nitrox section, arrows points to uneven staining and fragmented fibers. (d) Heliox section showing more uniform staining and less fragmentation.
