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.
