Dear Customer,

This Microlife fingertip pulse oximeter is a portable noninvasive device intended for spot-checking of the oxygen saturation of arterial hemoglobin (SpO2) and pulse rate of adults and pediatric patients. It is suitable for private use (at home, or on the go) as well as for use in the medical sector (hospitals, hospital-type facilities). It has been clinically proven to be of high precision during repeatability.

If you have any questions, problems or want to order spare parts please contact your local Microlife-Customer Service.

Use of this device is not intended as a substitute for a consultation with your doctor.

General Description

Oxygen saturation indicates the percentage of hemoglobin in arterial blood that is loaded with oxygen. This is a very important parameter for the respiratory circulation system. Many respiratory diseases can result in lower oxygen saturation within human blood.

Following factors can reduce oxygen saturation:Automatic regulation of organ dysfunction caused by anesthesia, intensive postoperative trauma, injuries caused by some medical examinations. These situations may result in light-headedness, asthenia and vomiting. Therefore, it is very important to know the oxygen saturation of a patient so that doctors can detect problems in a timely manner.

Measurement Principles

Principle of this fingertip pulse oximeter: A mathematical formula is established making use of Lambert Beer Law according to spectrum absorption characteristics of deoxygenated hemoglobin (Hb) and oxyhemoglobin (HbO₂) in red and near-infrared zones.

Operation principle of this device:Photoelectric oxyhemoglobin inspection technology is adopted in accordance with capacity pulse scanning and recording technology, so that two beams of different wavelength of lights (660 nm red and 905 nm near infrared light) can be focused onto a human nail tip through a clamping fingertype sensor. A measured signal obtained by a photosensitive element, will be shown on the display through process in electronic circuits and microprocessor.

Directions for Use

1. Insert the batteries as described in the «Inserting the batteries » section.
2. Insert one finger (nail side up; index or middle finger is recommended) into the finger opening of the device. Be sure to fully insert the finger so that the sensors are completely covered by the finger.
3. Release the device allowing it to clamp down on the finger.
4. Press the ON/OFF buttonto turn the device on.
5. Do not shake your finger during the test. It is recommended that you do not move your body whilst taking a reading.
6. Your measurement values will appear on the screen after a few seconds.
7. Remove your finger from the device.
8. The device will automatically switch off after approx. 8 seconds after the finger is removed from the device.

The height of the bar graph is an indication of the pulse and signal strength. The bar should be greater than 30% for a proper reading.

The device must be able to measure the pulse properly to obtain an accurate SpO measurement. Verify that nothing is hindering the pulse measurement before relying on the SpO₂ measurement.

The maximum application time at a single site should be less than 30 minutes, in order to ensure correct sensor alignment and skin integrity.

Inaccurate measurements may occur if:

• The patient suffers from significant levels of dysfunctional hemoglobin (such as carboxyhemoglobin or methemoglobin).
• Intravascular dyes such as indocyanine green or methylene blue have been injected into the patient.
• Used in the presence of high ambient light (e.g. direct sunlight). Shield the sensor area with a surgical towel if necessary.
• There is excessive patient movement.
• The patient experiences venous pulsations.
• The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
• The patient is in cardiac arrest or is in shock.
• Fingernail polish or false fingernails are applied.

Inserting the batteries

After you have unpacked your device, first insert the batteries. The battery compartment is on the bottom of the device. Remove the battery cover by sliding it in the direction shown. Insert the batteries (2 x 1.5 V, size AAA), thereby observing the indicated polarity.

Replace the batteries when the low power indicatorappears on the display.

Always replace both batteries at the same time.

Risk reminder

If the device detects your pulse rate is lower than 50 bpm, higher than 130 bpm or the SpO2 level is lower than 94%, there will be a warning sound alert.

Using the Lanyard

Thread the thinner end of the lanyard through the hanging hole at the rear end of the device.

9. Thread the thicker end of the lanyard through the threaded end before pulling it tightly.

Malfunctions and Actions to take

Cleaning and Disinfecting

Use an alcohol swab or cotton tissue moistened with alcohol (70% Isopropyl) to clean the silicone that touches the finger inside of the device. Also clean the finger being tested using alcohol before and after each test. Allow the device to dry thoroughly before use.

Never use abrasive cleaning agents, thinners or benzene for cleaning and never immerse the device in water or other cleaning liquids.
