WARNING Inspect the application site every two to three hours to ensure skin quality and correct optical
alignment. If the skin quality changes, move the sensor to another site. Change the application site at
least every four hours.
CAUTION • Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin and
carboxyhemoglobin may lead to inaccurate measurements.
• Interference can be caused by:
– High levels of ambient light or strobe lights or flashing lights (such as fire alarm lamps). (Hint:
cover application site with opaque material.)
– Electromagnetic interference.
– Excessive patient movement and vibration.

Signal Quality Indicator (Fast SpO
2
only)
The SpO
2
numeric is displayed together with a signal quality indicator (if configured and enough space
is available) which gives an indication of the reliability of the current values.
The level to which the triangle is filled shows the quality of the signal; the indicator below shows a
medium signal quality, the signal quality is at a maximum when the triangle is completely filled.
Assessing a Suspicious SpO
2
Reading
Traditionally, pulse rate from SpO
2
was compared with heart rate from ECG to confirm the validity of
the SpO
2
reading. With newer algorithms, such as FAST-SpO
2
, this is no longer a valid criteria
because the correct calculation of SpO
2
is not directly linked to the correct detection of each pulse.
When pulse rate is very low, or strong arrhythmia is present, the SpO
2
/Pleth pulse rate may differ from
the heart rate calculated from ECG but this does not indicate an inaccurate SpO
2
value.
If you doubt the measured SpO
2
, use the signal quality indicator (if available) or the pleth wave and
perfusion indicator instead to assess the signal quality.
NOTE With pulse oximetry, sensor movement, ambient light (especially strobe lights or flashing lights) or
electromagnetic interference can give unexpected intermittent readings when the sensor is not attached
to a patient. Especially bandage-type sensor designs are sensitive to minimal sensor movement that
might occur when the sensor is dangling.
