19 Monitoring Central Venous Oxygen Saturation
(ScvO
2
)
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
2
monitoring is intended for adult and pediatric patients.
