2) Set simulator as follows:
• ECG = Normal Sinus
• HR = 80 beats per minute (bpm)
• amplitude = 1.0 mV
• RESPIRATION = Normal Rest.
• rate = 20 breaths per minute (BPM)
• ohms = 1.0
• LEAD SELECT = II/RA-LL
• BASELINE IMPEDANCE = 500
7.2 Waveforms/Digital
Readouts/Tones
1) Verify the following:
• Waveform and HR correspond to data provided by simulator.
• Heart symbol (
♥
) blinks and pulse tone sounds for each QRS complex.
• White spike present at each QRS complex.
• RESP and HR digital readout correspond to settings of simulator.
2) Vary Tone Volume setting and verify that pulse tone volume changes.
3) Set Tone Volume to OFF, and verify that pulse tone stops.
7.3 Pacer Detection
1) Apply paced signal from simulator.
2) Verify that small “P” accompanies heart symbol (
P
♥
)
for every
detected, paced beat, blue spike appears for each paced signal, and
HR digital value agrees with pacer bpm setting.
3) Generate asystole condition in simulator, with pacer output still active.
4) Verify that ASY appears in ARR parameter box, an asystole alarm
sounds, and waveform is flatline with pacer pulses.
5) Disable pacer signal, and return simulator to setup above (section
7.1).
7.4 Lead-Off Indicators
1) One at a time, disconnect each ECG lead from simulator.
2)• For LL and RA electrodes, verify “Lead-Off” and “ECG Leads Invalid”
messages appear in message area, pulse tone ceases, *** replaces
digital heart rate in HR field.
• For V and RL electrodes, verify “Lead-Off” message, loss of V trace.
• For LA electrode, verify “Lead-Off” message only.
3) Reconnect all leads to simulator.
7.5 Alarm Function
This procedure also tests that the alarm function of the monitor, as
applicable to all other patient parameters, is operational in the monitor.
1) In Alarm Limits Table, set HR alarm parameters as follows:
• Upper limit = 110 bpm
• Lower limit = 40 bpm
•Alarm = ON
2) Set emulator to HR = 120 bpm.
3) Verify that monitor responds with following Serious Alarm indications:
