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-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
5
repetition.
