2. OVERVIEW
The pulse oxygen saturation is the percentage of HbO
2
in the total Hb in the
blood, so-called the O
2
concentration in the blood. It is an important bio-pa-
rameter for the respiration. A number of diseases relating to respiratory system
may cause the decrease of SpO
2
in the blood, furthermore, some other causes
such as the malfunction of human body’s self-adjustment, damages during
surgery, and the injuries caused by some medical checkup would also lead to
the difficulty of oxygen supply in human body, and the corresponding symp-
