Livers were oxygenated actively with a 95%O2/5%CO2 mixture or passively with ambient air (20%O2/0.03%CO2). (A) Oxygenator efficacy was demonstrated through a constant oxygen delivery rate (ODR) measured at the inflow to the portal vein as a function of the perfusate flow rate and gas composition. (B) The rate of oxygen exiting the liver (OER), measured in the vena cava, depicted the amount of oxygen remaining in the perfusate after passing through the liver. (C) The difference in oxygen delivery rate (ODR) and exit rate (OER) described the oxygen uptake rate by the liver (OUR), which declined with temperature and oxygen availability. Data are expressed as mean ± s.d. *Greater than passive oxygenation (p<0.05). **Greater than all other groups (p<0.05).
