10. Observe the following with leads II, III, aVR, aVF, and V:
On the patient monitor, the pacemaker icon with asterisk
appears in the ECG parameter box to denote pacemaker mode.
The patient monitor still displays an 80 ±1 bpm heart rate.
11. Remove the pacemaker pulse input and return the simulator to these
conditions:
Heart rate to 80 bpm.
Amplitude to 1.0 mV.
12. Select lead II for display in the top trace position if not already there.
13. Remove the RA leadwire from the patient cable.
14. Observe the following:
The monitor displays an RA FAIL message.
The monitor displays lead III in place of lead II.
15. Replace the RA leadwire. Observe lead II in the top trace position
again.
16. Print out a graph of ECG 1, lead II.
17. Observe that the waveform pulses are 1mV in amplitude both on the
printout and patient monitor display.
1. Connect a 12-lead patient cable to the patient monitor and simulator.
2. At the patient monitor, select the ECG parameter box.
3. At the ECG menu, select 12 LEAD ECG ANALYSIS.
4. Check that all 12 ECG waveforms display clearly, are noise-free, and
display an amplitude equal to the input voltage.
1. Set up simulator:
Set baseline impedance to 750Ω (or 1000Ω if using Marq II).
Set Δ (delta) R to 0.5Ω
Set lead select to I and II (or LL if using Marq II).
Set respiration rate to 30 breaths per minute.
2. Set up the monitor:
Turn the respiration waveform RR ON.
Set the respiration waveform to lead II.
3. Observe these conditions:
The monitor displays a distortion-free respiration waveform.
The monitor displays a respiration rate reading of 30 ±2 breaths
per minute.
4. Set the respiration waveform to lead I at the monitor, LA at the
simulator, and observe the same conditions as in step 3.
