Intended use

Only use the Beurer PO 40 pulse oximeter on humans to measure the arterial oxygen saturation (SpO) of haemoglobin, the heart rate (PRbpm) and the perfusion index (PI). The pulse oximeter is suitable for private use (at home) as well as for use in the medical sector (hospitals, medical establishments).

Getting to know your instrument

The Beurer PO 40 pulse oximeter provides a non-invasive measurement of the arterial oxygen saturation (SpO2), the heart rate (pulse rate) (PRbpm) and the perfusion index (PI). Oxygen 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. 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 saturation 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).

Warnings and safety notes

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.
Check the pulse oximeter regularly before use to ensure that there is no visible damage to the device and the batteries are still sufficiently charged. In case of doubt, do not use the device and contact Beurer customer services or an authorised retailer.
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.
– while transporting a patient other than within a medical establishment.
– 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 approx. >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 pain for people with circulatory disorders. Therefore do not use the pulse oximeter for longer than 30 minutes on one finger. This is essential to ensure correct sensor orientation and to safeguard the integrity of the skin.
The pulse oximeter displays an instantaneous measurement but cannot be used for continuous monitoring.
The pulse oximeter does not have an alarm function and is therefore not suitable for evaluating medical results.
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 medication 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.
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 incorrect or failed 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.
If the person moves while the measurement is being taken. Keep your hand, finger and body steady during the measurement.
For people with cardiac arrhythmia, the oxygen saturation level (SpO) readings and the heart rate (PRbpm) may be incorrect or the measurement may not be possible at all.
If an electronic surgical device or defibrillator is used, the functioning of the pulse oximeter may be impaired.
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 measurements.
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.
The measurement may be falsified in patients with an arterial catheter, hypotension, severe vascular constriction, anaemia or hypothermia
Protect the pulse oximeter from dust, shocks, moisture, extreme temperatures and explosive materials.
