Measurement Principle

This instrument measures the oxygen saturation (SpO2) in arte- rial blood and pulse rate continuously in a non-invasive method by applying optical principles.

With this instrument, SpO2 is defi ned by the following equation.

where

 

C (Hb):

Concentration of reduced hemoglobin

C (HbO2):

Concentration of oxyhemoglobin

The light-absorption characteristics of reduced hemoglobin (Hb) are very different from those of oxyhemoglobin. This instrument measures the changes in the absorption of red and infrared lights passing through the tissue to determine the SpO2 of the blood. Thus, this method is free from the effects of skin color, muscles, bones, and veins.
