The SpO2 module is intended for use as an aid to diagnosis
and monitoring. It must always be used in conjunction
with other signs and symptoms to make a diagnosis A clin-
ical assessment solely on the basis of the results provided
by the SpO2 module is not allowed.
If the accuracy of any reading is in doubt, first check the
patient's vital signs by alternate means. Then check the
SpO2 module for proper functioning.
The SpO2 module analyzes the signal for motion artifacts
and applies a number of algorithms, which suppresses
the majority. Conditions of extreme motion artifact are
indicated. Nevertheless, incorrect values caused by motion
artifacts (particularly those of long duration) cannot be
ruled out.
5.3.4 Applying the SoftTip SpO2 Sensor
The index finger is inserted into the SoftTip® sensor. The
cable should run over the back of the hand.
Within a few seconds the current oxygen saturation in
percent (%) will be indicated on the display.
Caution
Do not apply the SpO2 sensor to the same arm as
the blood pressure cuff. You may obtain incorrect or
inaccurate SpO2 values or no readings at all.
If the sensor is not correctly applied, some of the emitted
light may not be absorbed by the tissue, leading to inaccurate
measurements. Proper application of the sensor is essential for
obtaining good measurement results.
• Insert a finger (preferably the index, middle or ring finger)
into the SpO2 sensor until the end of the finger reaches the
finger stop. Do not use the thumb.
• The fingernail should be facing up. Make sure that long
fingernails do not interfere with proper sensor application.

Caution
Some nail polish colors (particularly dark shades)
or artificial fingernails may reduce light transmis­
sion through the tissue and affect pulse oximetry
accuracy. Remove nail polish or artificial finger
nails before application of the SpO2 sensor.
