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 indication, probe o and finger out indicarion,
data storage, transmitting and review etc. Please read this manual carefully before using the device.
Notes:
• The illustrations applied in the manual may di er 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 ), pulse rate (PR) and PI (Perfusion Index) of single adult, adolescent, child and infant 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 ) in red 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 di erent 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.
