Abstract

Venous oxygen saturation is a clinical tool which integrates the whole body oxygen uptake-to-delivery (VO2-DO2) relationship. In the clinical setting, in the absence of pulmonary artery catheter (PAC)-derived mixed venous oxygen saturation (SvO2), the central venous oxygen saturation (ScvO2) is increasingly being used as a reasonably accurate surrogate [1]. Central venous catheters (CVCs) are simpler to insert, and generally safer and cheaper than PACs. The CVC allows sampling of blood for measurement of ScvO2 or even continuous monitoring if an oximetry catheter is being used. The normal range for SvO2 is 68 to 77 % and ScvO2 is considered to be 5 % above these values [2].
