长期以来，饱和度测量一直用于以单个百分比值的形式提供关于组织内氧合水平的信息。虽然外周动脉血氧饱和度（SaO2）的测量提供了有关向大脑输送氧气的有用信息，但脑氧消耗和摄取的实际水平的测量将是治疗方向的更有用的指导。耗氧量是脑血流量（CBF）与动脉和静脉氧含量之差的乘积。因此，脑静脉饱和度的测量可以用作耗氧量的指标，并且已经显示出在具有受损脑血流动力学的患者的管理中是有用的临床参数（Garlick等人，1987年，Cruz等人，1991年）。
Saturation measurements have long been used to provide information about oxygenation levels within tissue in the form of a single percentage value. Whilst the measurement of peripheral arterial oxygen saturation (SaO2) provides useful information about the delivery of oxygen to the brain, a measure of the actual level of cerebral oxygen consumption and uptake would be a more useful guide for the direction of therapies. Oxygen consumption is the product of cerebral blood flow (CBF) and the difference between arterial and venous oxygen content. Measurements of cerebral venous saturation can therefore be used as an indicator of oxygen consumption and have been shown to be a useful clinical parameter in the management of patients with compromised cerebral haemodynamics (Garlick et al., 1987, Cruz et al., 1991).
