Silvercrest 290989 Instructions For Use And Safety page 20

- 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.
Protect the pulse oximeter from dust, shock, moisture, and extreme temperatures.
Keep out of areas with explosive substances.
Routinely inspect the pulse oximeter to ensure the device is not visibly damaged be-
fore use and the battery level is sufficient. When in doubt, do not use and contact
service or an authorised retailer.
