9-2. Measurement principle
This product measures the percentage of oxygenated hemoglobin (HbO
2
) in the blood. Two different
wa elengths of light are used to penetrate the skin of the fingertips into the ascular tissue. Oxygenated
hemoglobin (HbO
2
) and deoxygenated hemoglobin (Hb) absorb light of two different wa elengths
differently. A con ersion technology will con ert that difference into electrical signals. The oxygen
saturation (SpO
2
) will then be calculated according to the below formula.
