- Be sure the fingernail on the monitored finger is short enough so the finger pad covers
the sensor elements inside the housing.
- Keep the hand, finger and body still during measurement.
- Oxygen saturation and heart rate measurements may be false or impossible in
persons with arrhythmia.
- The pulse oximeter will display high measurements when carbon monoxide poison-
ing is present.
- To prevent false readings, keep bright light sources (e. g. fluorescent lamps or direct
sunlight) out of the immediate surroundings of the pulse oximeter.
- Measurements may be faulty or false in persons with low blood pressure, jaundice
or taking vasoconstriction medications.
- False measurements should be expected in patients who have received contrast
agents in the past, and in patients with haemoglobin abnormality. This particularly
applies to carbon monoxide poisoning and methaemoglobin poisoning caused by
e.g. local anaesthetics or due to methemoglobin reductase deficiency.
