Under normal circumstances, O 2 transport (TO 2 = cardiac output x arterial O 2 content) is regulated to provide sufficient O 2 to meet the demands of oxidative phosphorylation, quantified as the O 2 consumption (VO 2). When metabolic demands increase, TO 2 is augmented and in addition, the fractional extraction of the delivered O 2 by the tissues, the O 2ER, also increases, to levels as high as 0.80 at maximum VO 2.
