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.
− 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 approx. < 5 mm).
− on patients who are not steady at the site of application (e.g. trembling).
− near flammable or explosive gas mixtures.
• Using the pulse oximeter for long periods may cause pain for people with circula-
tory disorders. Therefore do not use the pulse oximeter for longer than approx. 2
hours on one finger.
• The pulse oximeter displays an instantaneous measurement but cannot be used for
continuous monitoring.
