4. Select the desired pace rate with the external pace rate switch on the defib/pacer front panel.

5. Select either asynchronous (continuous) or synchronous (demand) pacing with the

ASYNC/DMAND MODE key. The current operating mode will be shown by the green

indicator light.

In demand mode the QRS indicator will flash if R-waves are being detected properly for

synchronization. If the indicator does not flash, QRS sensing may not be occurring because of

artifact. In this case it is recommended that you switch to asynchronous mode.

6. Turn the CURRENT level switch to the 10 mA position.

7. Press the PACE STOP/START key to start pacing. The indicator will flash with each

delivered pace stimulus.

8. Increase the current slowly (by turning the CURRENT level switch clockwise) and observe

the ECG trace on the Prism screen for evidence of electrical capture (which should occur

between 60-100 mA). You should see a rhythm with pace flags.

In demand mode it is necessary to select a pace rate above the patient’s intrinsic rate before

determining the optimal pace current level.

9. Confirm mechanical capture by palpating the patient’s pulse or checking blood pressure. It is

also recommended that you monitor pulse oximetry for further confirmation of perfusion.

NOTE: The CHECK PACE ELECTRODES indicator flashes for each

failed pace pulse delivery attempt if the electrode-to-electrode

impedance is beyond the range of the pacer’s current output

capabilities. To correct, make sure that:

• both pacing electrodes are properly applied to the patient

• neither pacing electrode is dry or otherwise defective
