Product Overview

Thank you for purchasing HbO-SMART 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 HbO-SMART 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
Model:HbO-SMART

Intended Use

The HbO-SMART Fingertip Oximeter is intended for use in homes or hospitals for non-invasive measurement of oxygen saturation, pulse rate and perfusion index. The device can be used for both children andadults.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 (H bo2) in red light and near-infrared light zones. The pulse oximeter calculate Spot, PR and PI from the light intensity absorption difference by measuring the ratio of absorbed red and infrared light with each pulse.
