Directions for Use Monitoring 39
Perform SpO
2
monitoring with Nellcor option
1. Attach the sensor to the patient according to the sensor manufacturer's instructions,
observing all warnings and cautions.
2. When using a Nellcor SpO
2
sensor extension cable, inspect the cable before use.
Replace it if it shows any signs of wear, breakage, or fraying. Plug the sensor into the
cable and plug the cable into the Propaq monitor, or plug the sensor directly into the
monitor.
3. If the monitor SpO
2
receptacle has a locking ring, lock the connector in place by
turning the locking ring clockwise until it stops. For other connectors, make sure the
plug is all the way in.
4. From the Main Menu, press SpO
2
(or SpO
2
/CO
2
and then SpO
2
) 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).
At high magnification (4x, 8x), some waveforms may appear truncated. To view these
waveforms, reduce the size until the complete waveform appears.
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
:
WARNING Use only Nellcor accessories and sensors with the monitor with
Nellcor SpO
2
option, as listed in Welch Allyn Products and Accessories
(810-0409-XX).
Caution If you see the error message DEFECTIVE SpO
2
SENSOR, either the
sensor is not compatible with the monitor or the sensor is not working properly.
Check the Welch Allyn Products and Accessories (810-0409-XX) to be sure the
sensor is compatible. If compatibility is not a problem, try another sensor.
Note 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.
