Prolonged use of the pulse oximeter may
cause pain in persons with circulatory
disorders. Therefore do not use the pulse
oximeter on the same finger for longer than
approx. 2 hours.
Do not look directly into the housing during
measurement. The red light and the invisible
infrared light of the pulse oximeter is harmful
to the eye.
Failure to observe the following instructions
may result in faulty or failed measurements:
- Do not use nail polish, artificial nails or
other cosmetic on the monitored finger.
- Be sure the fingernail on the monitored fin-
ger 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 measure-
ments may be false or impossible in persons
with arrhythmia.
