4. From the Main Menu, press
SpO2
(or
SpO2/CO2
, then
SpO2
) to display the first SpO
2
menu similar to the following:
5. Press
SIZE
to adjust the waveform size for best viewing (1x, 2x, 4x, or 8x).
6. Adjust the placement of the sensor until a good SpO
2
waveform is displayed. A
waveform with artifact may cause erroneous oxygen saturation readings.
7. Press
MORE
to display the second SpO
2
menu:
8. Press RESPONSE to select the appropriate time required to measure SpO
2
:
Caution If you see the error message DEFECTIVE SpO2 SENSOR, either
the sensor is not compatible with the monitor or the sensor is not working
properly. Check the Welch Allyn Products and Accessories booklet (810-
0409-XX) to be sure the sensor is compatible. If compatibility is not a problem,
try another sensor.
The monitor displays STANDBY in the SpO
2
numeric window until it measures
and displays the SpO
2
value. As oxygen saturation increases and decreases,
the pitch of the heart tone rises and falls.
The Nellcor SpO
2
option periodically performs an internal adjustment which
causes the SpO
2
waveform to appear flat for a brief period.
At high magnification (4x, 8x), some waveforms may appear truncated. To
view these waveforms, reduce the size until the complete waveform appears.
