3-4 LIFEPAK 500 Automated External Defibrillator Operating Instructions
Using the LIFEPAK 500 AED
Patients with Implanted Pacemakers
If possible, place defibrillation electrodes away from the internal pacemaker generator. Treat this
patient like any other patient requiring emergency care. Pacemaker pulses may prevent advisement of
an appropriate shock, regardless of the patient's underlying rhythm.
Patients with Implanted Defibrillators
Apply the electrodes in the anterior-lateral position. Treat this patient like any other patient requiring
emergency care.
Alternate Anterior-Posterior Electrode Position
The electrodes may be placed in an anterior-posterior position as follows:
1 Place either the or + therapy electrode over the left precordium as shown in Figure 3-2. The upper
edge of the electrode should be below the nipple. Avoid placement over the nipple, the diaphragm,
or the bony prominence of the sternum if possible.
2 Place the other electrode behind the heart in the infrascapular area as shown in Figure 3-2. For
patient comfort, place the cable connection away from the spine. Do not place the electrode over the
bony prominences of the spine or scapula.
