19 Monitoring Central Venous Oxygen Saturation
(ScvO

)
19.1 ScvO

 Introduction
Central venous oxygen saturation (ScvO
2
) is measured across spectrophotometry. Spectrophotometry involves 
the use of light emitting diodes (LED) that produce light of various wavelengths in red and infrared spectra. The 
light is transmitted to the blood through a fiberoptic in the probe, reflected off the red blood cells and 
transmitted back through a separate fiberoptic to an optical module. The central venous oxygen saturation is 
calculated through the analysis of the reflected spectra.
ScvO

 monitoring is intended for adult and pediatric patients.
