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 is small in volume,low in power
consumption,convenient in operation and portable. With high-definition
display screen,the device is concise and fashion.It is only necessary for
patient to put one finger into probe for diagnosis, and the display screen will
directly show the SpO
2
value,pulse rate value,Perfusion Index value and
pulse waveform with the high veracity and repetition.
