9.5 Preparing for Pacing
1. Connect the electrode pads with pads cable, and then plug the pads cable into the therapy port.
2. Prepare the patient and apply the electrode pads to the patient. For details, refer to 5.4.1 Preparing the
Patient Skin and 5.4.3 ECG Measurement with Electrode Pads .
3. If pacing in demand mode, apply monitoring electrodes, and connect the ECG cable to the equipment. To
get the best monitoring signal, make sure there is adequate space between ECG electrodes and therapy
electrodes. For details, refer to
5.4.2 ECG Monitoring with Electrodes .
9.5.1 Demand Mode Pacing
To pace in demand mode pacing:
1. Switch the Mode Select knob to Pacer. Thus the pacing function is enabled in demand mode automatically.
ECG waveform of Lead II is displayed in the waveform area by default.
You can define [ Manual Therapy Access ] by selecting [ Manual Defib Setup ] from the Configuration Main
menu.You can also set [ Default Pacer Mode ] to define the default pacer mode by selecting [ Pacer Setup ]
from the Configuration Main menu.
2. Press the Lead Select button on the front panel to select a lead with an easily detectable R-wave.
3. Verify that white R-wave markers appear above the R-waves. If the R-wave markers do not appear or do not
coincide with the R-waves (for example above the T-waves), select another lead.
4. Use the Navigation knob to adjust the pacer rate, then press the Navigation knob. If necessary, select initial
pacer output.
5. Press the [ Start Pacing ] soft key to start pacing. The message “ Pacing ” appears in the pacer information
area.
6. Verify that white pace markers appear on the ECG waveform, as shown below:
7. Adjust pacer output. increase pacer output until cardiac capture occurs (capture is indicated by the
appearance of a QRS complex after each pace marker), and then decrease the output to the lowest level
that still maintains capture.
8. Verify the presence of a peripheral pulse.
You can temporarily withhold pace pulse and observe the patient’s underlying rhythm by pressing and holding
the [
4:1 ] soft key. This causes pacing pulse to be delivered at 1/4 of the defined pacer rate. To resume pacing at
set rate, release this key.
To stop pacing, press the [ Stop Pacing ] soft key. Pressing the [ Start Pacing ] soft key can resume pacing.
CAUTION
•
Routinely assess the patient’s cardiac output.
NOTE
•
Pacing will not start if there is a problem with the pads cable connection, pad patient connection, or
ECG monitoring electrodes connection. If any situation occurs, a message will appear in the pacer
information area to alert you that a lead is disconnected or that the electrode pads have a poor
connection.
