Overview
The pulse oxygen saturation is the percentage of HbO
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
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
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.

The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through
finger. The product is suitable for being used in family, hospital, oxygen bar, 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
