1 Introduction
1.1 Brief Introduction
Thank you for purchasing the handheld pulse oximeter for the functional oxygen saturation of
arterial hemoglobin (SpO
2
) and Pulse Rate (PR) measurement. The pulse oximeter features
PR tone modulation, data storage and data transmission capabilities. Please read the user
manual carefully before using this instrument.
Note:
•
The illustrations applied in the manual may differ slightly from the actual device.
•
The specifications are subject to change without prior notice.
•
The device is designed of handheld structure and please be sure not to turn upside
down when using it.
1.2 Intended Use
The MD300I pulse oximeter is a portable non-invasive device intended for spot-checking of
oxygen saturation of arterial hemoglobin (SpO
2
) and pulse rate of adult and pediatric patient
at home and hospital (including clinical use in internist/surgery, Anesthesia, intensive care
and etc). It is not for continuous monitoring.
1.3 Measurement Principle
Principle of the oximeter is as follows: A mathematical formula is established making use
of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive
hemoglobin (RHb) and Oxyhemoglobin (HbO2) in glow and near-infrared zones. Operation
principle of the instrument: Photoelectric Oxyhemoglobin Inspection Technology is adopted
in accordance with Capacity Pulse Scanning and Recording Technology, so that two beams
of different wavelength of lights (660nm glow and 940nm near infrared light) can be focused
onto a human nail tip through a clamping finger-type sensor. A measured signal obtained by a
photosensitive element, will be shown on the oximeter’s display through process in electronic
circuits and microprocessor.
