The oxygen saturation is the percentage of HbO
in the total Hb in the blood, so-called the
2
O
concentration in the blood, it is an important physiological parameter for the respirato-
2
ry and circulatory system. A number of diseases related to respiratory system may cause
the decrease of SpO
in the blood, furthermore, some other causes such as the malfunc-
2
tion 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 symptoms would appear as a consequence, such as vertigo,

prompt information of patients' SpO
is of great help for the doctor to discover the po-
2
tential danger, and is of great importance in the clinical medical field.
Insert the finger when measuring, the device will directly display the SpO
value mea-
2
sured, it has a higher accuracy and repeatability.
