The pulse oxygen saturation is the percentage of
Hb
O
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 s aturation with the high veracity and repetition.

The Pulse Oximeter can be used
in
measur ing t he pulse oxygen s aturation and pulse rat e through
finger. The product is suitable for being used
in
family, hospital, o xygen b ar, community healthcare,
physical care
in
sports (It can be used before or after doing sports, and
it
is not recommended to use
the device during the process of having sport ) and etc.
The problem of overrating would emerge when the patient is suffering from toxicosis which
caused by carbon monoxide, the device is not recommended to be used under this circumstance.
