2. Overview
The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the
blood, in other words the O2 concentration in blood. It is an important bio-
parameter for respiration. A number of diseases relating to the respiratory
system may cause a decrease of SpO2 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
