In healthy tissues, decreases in oxygen delivery (QO2 = cardiac output X arterial O2 content) do not lower oxygen consumption (VO2) because tissue O2 extraction increases proportionately. When delivery is reduced below a critical threshold, VO2 falls because tissue extraction exceeds a critical thre
