- The pulse oximeter will display high measure-
ments when carbon monoxide poisoning
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 haemoglo-
bin abnormality. This particularly applies to
carbon monoxide poisoning and methae-
moglobin poisoning caused by e.g. local
anaesthetics or due to methemoglobin re-
ductase deficiency.
Protect the pulse oximeter from dust, shock,
moisture, and extreme temperatures.
Keep out of areas with explosive substances.
