1 INTRODUCTION
1.1 Brief Introduction
Thank you for purchasing the MD300K2 pulse oximeter. The main functions of the device
include SpO , PR and PI (Perfusion Index) measurements, visual and audible alarm, probe

off and finger out indication, data storage, transmitting and review etc. Please read this
manual carefully before using the device.
Notes:
• The illustrations applied in the manual may differ slightly from the actual device.
• The device is designed of handheld structure, please be sure not to turn upside down
when using it.
1.2 Intended Use
The MD300K2 Pulse Oximeter is intended for continuous monitoring, spot-checking of
oxygen saturation (SpO
and child patients in hospitals and clinics.
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 (HbO
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 red and 905nm 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.
