2 Overview
The pulse oxygen saturation is the percentage of HbO2 in the total Hb in
the blood, so-called the O2 concentration in the blood. It is an important
bio-parameter for respiration. A number of diseases relating to respiratory
system may cause a decrease of SpO2 in the blood.
2.1 Features
A. Operation of the product is simple and convenient.
B. The product is compact, light in weight and convenient to carry.
C. Low power consumption
2.2 Major applications and scope of application
The Pulse Oximeter can be used in measuring the pulse oxygen saturation

and pulse rate through finger. The product is suitable for being used at
home, in the hospital, at an oxygen bar, in community healthcare, and
for physical care in sports (it can be used before or after sports, it is not
recommended to use the device during sport) and etc.
2.3 Environment requirements
Storage Environment
a) Temperature :-40°C +60°C
b) Relative humidity :5% 95%
c) Atmospheric pressure :500hPa 1060hPa
Operating Environment
a) Temperature:10°C 40°C
b) Relative Humidity :30% 75%
c) Atmospheric pressure:700hPa 1060hPa
3 Principle
Principle of the Oximeter is as follows: using Lambert Beer Law and
according to Spectrum Absorption Characteristics of Reductive Hemoglobin
(Hb) and Oxyhemoglobin (HbO2) in glow & near-infrared zones. Operation
principle of the device is: Photoelectric Oxyhemoglobin Inspection
Technology is adopted in accordance with Capacity Pulse Scanning &
Recording Technology, so that two beams of different wavelength of lights
can be focused onto human nail tip through perspective clamp finger-type
sensor. Then the measured signal can be obtained by a photosensitive
element, information acquired through which will be shown on screen.
