38 Monitoring Welch Allyn Propaq CS Vital Signs Monitor
to the sensor, the patient is in cardiac arrest or shock, or the patient has hypotension,
severe vasoconstriction, severe anemia, or hypothermia.
Perform SpO
2
monitoring with Masimo option
1. Attach the sensor to the patient according to the sensor manufacturer's instructions,
observing all warnings and cautions.
2. Inspect the Masimo SpO
2
cable. 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.
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 monitor self-calibrates the SpO
2
channel whenever the monitor is first turned on
or a sensor is first connected to the SpO
2
channel.
3. From the Main Menu, press SpO
2
(or SpO
2
/CO
2
and then SpO
2
) to display the SpO
2
menu similar to the following:
4. Press SIZE to adjust the waveform size for best viewing (1x, 2x, 4x, or 8x).
5. Adjust the placement of the sensor until a good SpO
2
waveform is displayed. A
waveform with artifact may cause erroneous oxygen saturation readings.
6. Set alarm limits according to your hospital’s standards.
7. If patient movement interferes with measurements, consider the following possible
solutions:
• Be sure the sensor is secure and properly applied.
• Use a new sensor with fresh adhesive backing.
• Select a different type of sensor.
• Move the sensor to a less active site.
WARNING Use only Masimo accessories and sensors with the monitor with
Masimo SpO
2
option as listed in Welch Allyn Products and Accessories
(810-0409-XX).
Note To help minimize false alarms, the Propaq monitor briefly delays or "holds off"
triggering both audible and visual alarms for limit violations for SpO
2
% and Pulse
Rate for 10 seconds. After the alarm hold-off period begins, if the monitor detects
that the patient’s vital sign has returned to acceptable limits, the monitor cancels
the alarm hold-off. The next time a vital sign limit is violated, the monitor starts a
new hold-off period.
The “averaging time” for SpO
2
measurements is fixed at eight seconds.
