Mixed venous oxygen saturation (SvO2) has been established as a useful guide in observing whole body oxygenation. Since SvO2 provides limited information about adequate tissue oxygenation for a specific organ, the usefulness of central venous saturation (ScvO2) as a guide was analysed, which is a less invasive parameter. In 19 ICU patients 44 pairs of blood samples were drawn from a separate central venous catheter and from the tip of an SG-catheter. The correlation of oxygen partial pressures was 0.687 and the correlation of the saturation reached 0.779. The calculation of venous admixture showed a correlation of 0.901. It is concluded that ScvO2 yields adequate information on the oxygen saturation of venous return.
混合静脉血氧饱和度（SvO2）已被确立为观察全身氧合的有用指标。由于SvO2提供的关于特定器官充分组织氧合的信息有限，因此分析了中心静脉血氧饱和度（ScvO2）作为指标的有用性，它是一个侵入性较小的参数。对19例重症监护病房患者，从一根单独的中心静脉导管和一根SG导管尖端采集了44对血样。氧分压的相关性为0.687，饱和度的相关性达到0.779。静脉血掺杂计算显示相关性为0.901。得出的结论是，ScvO2能提供关于静脉回流血氧饱和度的充分信息。
