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-parameter 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 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' SpO
2
is 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.
