9.5.1 Demand Mode Pacing
To pace in demand mode:
1. Turn the Mode Select knob to the Pacer position. 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 access manual therapy directly, by confirmation or by password, which can be defined through
configuration management. The default setting is [ Direct ].
‹
If [ Manual Therapy Access ] is set to [ Direct ], the equipment directly enters Pacer mode when the Mode Select
knob is switched to Pacer.
‹
If [ Manual Therapy Access ] is set to [ Confirmed ], a dialog box pops up when the Mode Select knob is
switched to Pacer. You have to confirm whether to enter Pacer mode or not.
‹
If [ Manual Therapy Access ] is set to [ Password ], a dialog box pops up, requiring the user to enter a password,
when the Mode Select knob is switched to Pacer. The equipment enters Pacer mode only after correct
password is entered.
2. Select a lead with an easily detectable R-wave.
3. Verify that white R-wave markers appear above the R-waves, as shown in the figure below. 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. Select pacer rate. If necessary, select initial pacer output. To select pacer rate or pacer output, rotate the Navigation
knob to select an appropriate value and press it to confirm the selection. Do not forget to press the Navigation
knob to exit the setting after desired value is selected.
5. Press the [ Start Pacing ] soft key to start pacing. The message “ Pacing ” appears in the pacer information area. .
NOTE
z
Pacing will not start if there is a problem with the pads cable connection, pad patient connection, or ECG
monitoring electrodes connection. If either situation occurs, a message will appear in the pacer information
area to alert you that a lead is disconnected or that the pads have a poor connection.
6. Verify that white pacing 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 pacing marker), and then decrease the output to the lowest level that still maintains
capture.
