Figure 3. Arteriovenous difference in oxygen tension (A-VD_O2) was greater than arteriovenous difference in glucose (A-VD_GLUCOSE) except during cooling when A-VD_GLUCOSE of the control animals was greater than A-VD_O2.

A-VD_O2 in the CO-treated group was higher at 3 and 6 hours after CPB. A-VD_GLUCOSE was higher in the air group at baseline, during cooling and rewarming on CPB and immediately after CPB. While there were trends in A-VD_O2 and A-VD_GLUCOSE values between air and CO-treated animals, no significant differences were observed. Data represent the means ± SD of 6 animals/group.
