Functional Verification
Welch Allyn Micropaq Monitor
ECG Test
1.
Turn on power to the ECG simulator.
2.
Connect the ECG cable to the monitor and to the ECG simulator.
3.
Set the ECG simulator for a normal sinus rhythm.
Confirm that the monitor displays a normal sinus rhythm ECG waveform with a heart
rate that is the same (± 4 bpm) as the input of the ECG simulator.
4.
Conduct an ECG Lead Fail test:
a.
Remove the far left (LA) lead from the simulator. A skeletal torso appears in the
monitor display, with five dots arrayed on it.
b.
In the monitor display, verify that the dot corresponding to the LA electrode is
blinking. Reconnect the LA lead to the simulator.
c.
Remove each simulator lead in turn. The corresponding dot blinks with each
removed simulator lead, and stops blinking when the switch is released.
5.
Disconnect the ECG cable from the simulator and monitor, and then turn off power to
the simulator.
Model 402: Testing is complete. Remove the monitor battery.
Model 404: Go on to the next section to test SpO
2
.
SpO
2
Test (Model 404 Only)
1.
Turn on power to the SpO
2
simulator.
2.
Connect the SpO
2
cable to the monitor and the SpO
2
sensor.
3.
Apply the SpO
2
sensor to the SpO
2
simulator optical finger.
4.
Set the SpO
2
simulator manufacturer type (“MAKE”) as appropriate: Masimo or
Nellcor.
5.
Set the simulator output to SpO
2
saturation 94 percent and pulse rate 60 beats per
minute (with no motion artifact selected).
Confirm the following:
•
The monitor displays SpO
2
data and the pulse amplitude indicator is moving.
•
The displayed saturation = 94 percent ± 4 counts.
•
The displayed pulse rate = 60 ± 4 bpm.
6.
Disconnect the sensor from the simulator and the cable, disconnect the SpO
2
cable,
and remove the monitor battery.
