2. Intended use
Only use the Beurer PO 80 pulse oximeter on humans to measure the arterial oxygen saturation (SpO₂) of haemoglobin and the heart rate (pulse rate). The
pulse oximeter is suitable for private use (at home) as well as for use in the medical sector (hospitals, medical establishments).
3. Getting to know your device
The Beurer PO 80 pulse oximeter provides a non-invasive measurement of the arterial oxygen saturation (SpO
saturation indicates the percentage of haemoglobin in arterial blood that is loaded with oxygen. Therefore it is an important parameter for assessing
the respiratory function. If the values fall below or exceed your individually set alarm limits, you receive an acoustic warning. Thanks to the integrated
memory, it is possible to record data continuously for up to 24 hours. The pulse oximeter can be connected to a PC using the integrated USB connection.
The SpO software enables you to carry out a detailed evaluation of your records.
2
To take a measurement, the pulse oximeter uses two rays of light with differing wavelengths, which strike the finger inserted inside the housing.
A low oxygen saturation value generally indicates underlying illnesses (respiratory diseases, asthma, heart failure etc.). People with a low oxygen satura-
tion value are more likely to experience the following symptoms: shortness of breath, increased heart rate, weakness, nervousness and outbreaks of
sweating. If oxygen saturation is known to be chronically diminished, it requires monitoring using the pulse oximeter under medical supervision. If you
have acutely diminished oxygen saturation, with or without the accompanying symptoms, you must consult a doctor immediately as it could lead to a life-
threatening situation. The pulse oximeter is particularly suitable for patients at risk such as people with heart disease or asthma, but also for athletes and
healthy people who exercise at high altitude (e.g. mountaineers, skiers or amateur pilots).

5. Warnings and safety notes
Read these instructions for use carefully. Non-observance of the following information may result in personal injury or material damage. Store these
instructions for use and make them accessible to other users. Make sure you include these instructions for use when handing over the device to third
parties.
WARNING
• Check to ensure that the package contains all the parts that should be included in the delivery.
• Before use, ensure that there is no visible damage to the unit or accessories. When in doubt, do not use the unit and contact your dealer or the cus-
tomer service address provided.
• Do not use any additional parts that are not recommended by the manufacturer or offered as equipment.
Under no circumstances should you open or repair the device yourself, as faultless functionality could no longer be guaranteed thereafter. Failure to
•
comply will result in voiding of the warranty. For repairs, please contact Beurer customer services or an authorised retailer.
Do NOT use the pulse oximeter
− if you are allergic to rubber products.
− if the device or the finger you are using is damp.
− on small children or babies.
− during an MRI or CT scan.
− whilst taking a blood pressure measurement on the same arm using a cuff.
− on fingers that have nail varnish on, are dirty or have a plaster or other dressing on them.
− on large fingers that do not fit into the device easily (fingertip: width approx. > 20 mm, thickness >15 mm).
− on fingers with anatomical changes, oedemas, scars or burns.
− on fingers that are too small, as with small children for example (width approx. < 10 mm, thickness < 5 mm).
− on patients who are not steady at the site of application (e.g. trembling).
− near flammable or explosive gas mixtures.
• Using the device for long periods may cause discomfort or pain for people with circulatory disorders. Therefore do not use the pulse oximeter for longer
than 2 hours on one finger.
• Do not self-diagnose or self-medicate on the basis of the measurements without consulting your doctor. In particular, do not start taking any new medi-
cation or change the type and/or dosage of any existing medication without prior approval.
• Do not look directly inside the housing during the measurement. The red light and the invisible infra-red light in the pulse oximeter are harmful to your
eyes.
• This device is not intended for use by people (including children) with restricted physical, sensory or mental skills or a lack of experience and/or a lack
of knowledge, unless they are supervised by a person who has responsibility for their safety or they receive instructions from this person on how to use
the device. Children should be supervised around the device to ensure they do not play with it.
• Neither of the displays for the pulse wave and pulse bar allows the strength of the pulse or circulation to be evaluated at the measurement site. Rather,
they are exclusively used to display the current visual signal variation at the measurement site and do not enable reliable diagnostics for the pulse.
Non-observance of the following instructions can lead to inaccurate or incorrect measurements.
• There must not be any nail varnish, artificial nails or other cosmetics on the finger to be measured.
• Ensure that the finger nail on the finger to be measured is short enough that the fingertip covers the sensor element in the housing.
• Keep your hand, finger and body steady during the measurement.
• For people with cardiac arrhythmia, the measurement values of SpO₂ and the heart rate may be incorrect or the measurement may not be possible at
all.
In cases of carbon monoxide poisoning, the pulse oximeter displays a measurement value that is too high.
•
• To avoid falsifying the measuring result, there should not be any strong light sources (e.g. fluorescent lamps or direct sunlight) in the immediate vicinity
of the pulse oximeter.
• People with low blood pressure, who suffer from jaundice or take medication for vascular contraction, may experience incorrect or falsified measure-
ments.
• Incorrect measurements are likely for patients who have been administered medical dye in the past or for those who have abnormal haemoglobin levels.
This applies in particular for cases of carbon monoxide poisoning and methaemoglobin poisoning, which can occur for example from the administration
of local anaesthetics or from an existing methaemoglobin reductase deficiency.
• Protect the pulse oximeter from dust, shocks, moisture, extreme temperatures and explosive materials.
Notes on handling rechargeable batteries
• If your skin or eyes come into contact with fluid from the battery cell, flush out the affected areas with water and seek medical assistance.
• Choking hazard! Small children may swallow and choke on rechargeable batteries. Store rechargeable batteries out of the reach of small
children.
• Observe the plus (+) and minus (-) polarity signs.
• If a battery has leaked, put on protective gloves and clean the battery compartment with a dry cloth.
• Protect batteries from excessive heat.
• Risk of explosion! Never throw batteries into a fire.
• Do not disassemble, split or crush the rechargeable batteries.
• Only use chargers specified in the instructions for use.
• Batteries must be charged correctly prior to use. The instructions from the manufacturer and the specifications in these instructions for use
regarding correct charging must be observed at all times.
• Fully charge the battery prior to initial use.
• In order to achieve as long a battery service life as possible, fully charge the battery at least twice per year.
