INSTRUCTION MANUAL FOR PULSE OXIMETER/
MANUAL DE USO PARA PULSIOXÍMETRO
Model/Modelo: PX-03
2.3 Major applications and scope of application
The Pulse Oximeter can be used to measure human Hemoglobin Saturation and
pulse rate through finger, and indicate the pulse intensity by the bar-display. The
product is suitable for use in family, hospital
（
Ordinary sickroom
）
, Oxygen Bar,
social medical organizations and also the measure of saturation oxygen and pulse
rate.
The product is not suitable for use in continuous supervision for
patients.
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.

3 Principle and Caution
3.1 Principle of measurement
Principle of the Oximeter is as follows: An experience formula of data process is
established taking use of Lambert Beer Law according to Spectrum Absorption
Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO
2
) in glow
& near-infrared zones. Operation principle of the instrument 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.
