A Common Knowledge for SpO

2

Measurement

1 Meaning of SpO

2

SpO

2

is the saturation percentage of oxygen in the blood,

so called O

2

concentration in the blood; it is defined by the

percentage of oxyhemoglobin (HbO

2

) in the total

hemoglobin of the arterial blood. SpO

2

is an important

physiological parameter to reflect the respiration function;
it is calculated by the following method:

SpO

2

= HbO

2

/ (HbO

2

+Hb)×100%

HbO

2

are the oxyhemoglobins (oxygenized hemoglobin),

Hb are those hemoglobins which release oxygen.

2 Principle of Measurement

Based on Lamber-Beer law, the light absorbance of a given
substance is directly proportional with its density or
concentration. When the light with certain wavelength
emits on human tissue, the measured intensity of light after
absorption, reflecting and attenuation in tissue can reflect
the structure character of the tissue by which the light
