Abstract
The curve presenting the relation between oxygen consumption (V̇o2) and blood flow (BF) can be divided into two parts (see Fig. 1). The first one shows a proportionality between the values, supporting the hypothesis of a metabolic control of blood flow. In the second portion a distinct saturation of oxygen consumption is reached, A variation in O2 consumption is then possible independent of flow, thereby changing the amount of O2 extraction. In this upper range a metabolic control of blood flow becomes insufficient to explain changes in the horizontal course of the pressure-flow curve, generally called “autoregulation of blood flow” (see Fig. 3).
