• Ensure that the finger nail on the finger to be measured is short enough that the
fingertip covers the sensor elements 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 measure-
ment value that is too high.
• To avoid falsifying the measurement, 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.
• Protect the pulse oximeter from dust, shocks, moisture, extreme temperatures and
explosive materials.
