Product Overview

Thank you for purchasing LOX100 Fingertip Pulse Oximeter.The main use of this product is for measuring patients oxygen saturation (SpO2), Pulse Rate (PR) and Perfusion Index (PI). Perfusion Index (PI) is related to the strength of the patients pulse at the site of measurement. PI is measured as a percentage(%) and the optimal value is 20% indicating a very strong pulse. The product includes both visual and audible alerts for high/low SpO2 and Pulse Rate. The applied part of the LOX100 is constructed from silica gel. Please carefully read the User Manual before use.
1.1 Appearance

1.2 Name and Model
Name: Fingertip pulse oximeter

Intended Use

The LOX100 Fingertip Oximeter is intended for use in homes or hospitals for non-invasive measurement of oxygen saturation, pulse rate andperfusion index. The device can be used for both children and adults.This device is intended only for spot checking.

Principles of measurement

The measuring principles of pulse oximeter is based on Lambert-Beer law, The spectrum absorption characteristics is different of Reductive hemoglobin(RHb) and Oxyhemoglobin (Hbo2) in red light and nearinfrared light zones. The pulse oximeter calculate Spo2, PR and PI from the light intensity absorption difference by measuring the ratio of absorbed red and infrared light with each pulse.
