Myocardial tissue Po2 in the carbogen-treated non-ischemic mouse heart. WT mice were subjected to carbogen (95% O2 plus 5% CO2) treatment and in vivo EPR oximetry was performed. After 3-day carbogen breathing, myocardial tissue Po2 increased significantly compared to room air-treated mouse heart. *p<0.05 vs. room air control. N=6/group.
