This Fingertip Pulse Oximeter is a non-invasive medical device intended to quickly and precisely measure the oxygen

saturation in arterial haemoglobin (SpO2) and Pulse Rate (PR). For use in hospital, clinical and home environments.

Operating principle

Oximeters use a series of standardised principles to establish SpO2 and Pulse Rate. By using Lambert Beer's Law of Spectrum

Absorption Characteristics of Reductive Haemoglobin and Oxyhaemoglobin (HbO2) in visible and near-infrared light

wavelengths (660nm and 940nm respectively) in combination with Photoelectric Oxyhaemoglobin Inspection Technology with

Capacity Pulse Scanning and Recording Technology, the two diﬀerent wavelengths of light can be focused onto a human finger

nail through a clip-on finger sensor (2 in the diagram below). The signal is measured using a photosensitive element (1 in the

diagram below) and displayed as human readable data on a screen after processing through electronic circuits and a

microprocessor.

Operating Instructions

Installing the batteries and set up

1. Remove the battery compartment cover.

2. Insert two 1.5v AAA alkaline batteries (included) into the battery compartment. Ensure correctly alignment of the polarity

(positive and negative ends) of the batteries with the markings on the Oximeter. Incorrect insertion may cause damage to the

instrument.

Do NOT use rechargeable batteries as the output voltage is 1.3v per battery, not the required 1.5v. Only use good

quality, branded Alkaline AAA batteries and never mix old batteries with new batteries.

3. Close the battery compartment cover.

4. If you have an OxiPro 2 or 3 you may wish to check the pre-set alarm values meet your requirements and adjust if

necessary, instructions are given in Section 6 of this manual (not available on the OxiPro 1).

Performing a measurement

Remove nail polish or false nails before use as these will aﬀect the accuracy of the reading.

1. Sit or lie down, remaining still until your body is relaxed.

2. Taking note of the picture below, squeeze the clamp to separate the two halves of the Oximeter.

3. Insert your index or middle finger into the Oximeter as far as it will go, with the finger nail facing the side with the screen.

4. Press the power button on the front of the Oximeter to turn it on.

5. After a few seconds your measurements will be displayed on screen. Please note it may take up to 60 seconds for the

readings to stabilise, readings should be taken when the blood oxygen value is stable for 5 seconds or longer. If the Oximeter is

powered on but no measurements are shown please see the Trouble Shooting section 12 of this user manual.

6. If you wish to rotate the orientation of the values displayed on screen see Section 5 of this user manual.

7. To turn oﬀ the Oximeter, simply remove it from your finger and it will turn oﬀ automatically after 8 seconds.

8. Please replace the batteries when the battery symbol on screen shows low.

General Description

Haemoglobin saturation is the percentage between the

capacity of oxyhaemoglobin (HbO2) that compounded with

oxygen and that of all combinative haemoglobin (Hb) in

blood. In other words, it is the saturation of oxyhaemoglobin

in blood. It is a very important physiological parameter for

Respiratory and Circulation Systems. Many respiratory

diseases could reduce haemoglobin saturation in human

blood. Moreover, factors such as Automatic Organic

Regulation Malfunction caused by anaesthesia or trauma from

a major operation or examination can also cause problems in

oxygen supply, which might reduce human haemoglobin

saturation. As a result, symptoms such as migraine, vomiting

and asthenia might appear in patients. Hence, it is very

important to quickly know the haemoglobin saturation of

patients in clinical environments.

The fingertip pulse Oximeter is non-invasive, features low

power consumption, simple operation and portability. It is

only necessary for the patient to put one finger into the

photoelectric sensor for diagnosis and the display will directly

show the measured value of haemoglobin saturation. The

precision and repeatability of the Oximeter has been proven in

clinical trials.

When inserting your finger, the finger nail surface must face the

surface closest to the display, away from the light source.

To maintain good hygiene please use medical alcohol to clean the

rubber before each test and clean the tested finger with medicl alcohol

before and after the test. The rubber inside the Oximeter is of medical

standard which is non-toxic and anti-allergenic.

Features

• Displays SpO2, Pulse Rate (PR) and Perfusion Index (PI) (PI not on the OxiPro 1)

• Two-colour OLED display with six diﬀerent display modes on OxiPro 2 and 3, LED screen on the OxiPro 1

• The OXIPRO 3 model features an accelerometer which enables the information on the screen to rotate based on the

position of the patient. (Not on OXIPRO 1 & 2 models)

• Low-power consumption; more than six hours continual operation with two alkaline AAA batteries

• Low voltage indicator

• If a finger is not inserted, the product will enter standby mode after 8 seconds

• Small, light and portable

Display modes (NOT available on the OxiPro 1)

You can change the orientation of the values displayed on screen (display mode). When powered up, click the power button

once to change to the next display screen (please note: if you press and hold the power button instead of clicking it you will

enter the menu system shown in Section 6 below). Repeat the process to rotate between the six options shown below.

Please note: the OXIPRO 3 is equipped with an accelerometer and only features display modes 1 to 4 below. Screen

shots are for reference only and may diﬀer slightly from those on the Oximeter.

Setting options and alerts (NOT available on the OxiPro 1)

1. Press and hold the power button for >3 seconds until you enter the parameter setup menu, shown in the Menu 1 diagram

below. Clicking the power button moves the "*" between the menu options, pressing and holding the power button selects the

options to adjust.

2. To change the alarm settings, press and and hold the power button for >3 seconds when the "*" symbol is shown next to

"Alm Setup" as shown in the Menu 1 diagram below. This will enter Menu 2, shown below. Click the power button until the "*"

symbol is next to the option you wish to change. To adjust the option press and hold the power button and the numbers will

change.

3. To exit the menu and confirm your changes, click the power button until the "*" is next to "Exit", then press and hold the
