2 Overview

The pulse oxygen saturation is the percentage of HbO2in the

total Hb in the blood, so-called the O2concentration in the

blood. It is an important bio-parameter for the respiration. A

number of diseases relating to respiratory system may cause

the decrease of SpO2in 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 symptoms would appear as a consequence,

such as vertigo, impotence, vomit etc. Serious symptoms

might bring danger to human's life. Therefore, prompt

information of patients' SpO2is of great help for the doctor

to discover the potential danger, and is of great importance

in the clinical medical field.

The Pulse Oximeter features in small volume, low power

consumption, convenient operation and being portable.It is

only necessary for patients to put one of his fingers into a

probe for diagnosis, and a display screen will directly show

the measured value of pulse oxygen saturation with the high

veracity and repetition.
