Oxygen Consumption and Oxygen Extraction of the Feline Liver under Different Types of Induced Hypoxia
Under normal blood flow extraction of O2 by the liver is less than 40% of the oxygen supplied. This ratio of consumed to supplied O2 increases drastically when O2 supply diminishes with blood flow. For instance an O2 extraction greater than 95% is reached during relative ischaemia (Lutz et al, 1975). The experiments reported below were performed to test the mechanism of this extremely high O2 extraction, which is seen otherwise only in the coronary circulation.
