What This Guide Helps With

Identifying and correcting AED readiness concerns caused by opened, damaged, used, missing, disconnected, improperly stored, or expired electrode packages.

Step-by-Step Troubleshooting

1. Ensure Patient Safety First

Do not troubleshoot questionable electrodes while the AED Plus is the only defibrillator available for an active emergency.

If the issue is discovered during patient care:

Expected outcome: Emergency care continues without relying on electrodes of uncertain condition.

Continue Clinical Engineering troubleshooting only after emergency coverage has been restored.

2. Confirm the Reported Electrode Condition

Inspect the electrode package without opening a sealed replacement.

Determine whether the package is:

Expected outcome: The exact reason the electrode set is unsuitable or questionable is documented.

An opened, used, damaged, or expired package cannot be restored to service. Replace it and stop troubleshooting that electrode set.

3. Verify the Correct Electrode Type

Confirm that the electrodes are approved and compatible with the AED Plus.

Common compatible configurations include:

Do not substitute AED 3 CPR Uni-padz or electrodes intended only for another defibrillator model.

Check the package labeling, connector style, part number, and facility-approved supply list.

Expected outcome: The replacement electrodes are confirmed as compatible with the specific AED Plus configuration.

ZOLL identifies CPR-D-padz as the adult electrode system used with the AED Plus and specifies pediatric electrodes for patients under eight years old or under 55 pounds when the device supports pediatric use.

4. Check the Printed Expiration Date

Read the expiration date directly from the electrode package.

Do not rely only on:

Remove the package from service when the printed expiration date has passed, even when the package remains sealed and appears normal.

Expected outcome: Only electrodes within their manufacturer-marked expiration period remain assigned to the AED.

ZOLL states that freshly opened, undamaged electrodes within their expiration date should be used. CPR-D-padz are marketed with a five-year shelf life, but the date printed on the individual package controls replacement.

5. Inspect the Sealed Package

Verify that the foil or protective package is fully sealed.

Check for:

Do not press, bend, or manipulate the package excessively during inspection.

Expected outcome: The installed electrode package is unopened, dry, intact, and free from visible damage.

Replace any questionable package. A compromised seal may allow the conductive gel to dry or become contaminated.

6. Inspect the Electrode Cable and Connector

Check the exposed cable from the package to the AED connector.

Look for:

Do not open the electrode package to inspect the pads themselves.

Expected outcome: The external cable is undamaged and the connector is fully seated.

ZOLL directs that the electrode cable remain connected to the AED Plus and be checked when the device displays a red readiness indicator or emits a warning tone.

7. Replace the Questionable Electrode Package

Obtain a new, facility-approved electrode package.

Before installation:

Connect the electrode cable securely and place the sealed package inside the AED Plus cover without crushing or sharply bending it.

Expected outcome: A compatible, sealed, undamaged, and unexpired electrode package is installed.

Do not reuse a package that was opened during a previous rescue, even when the pads were not applied.

8. Perform the AED Plus Setup and Check-Out Test

After replacing the electrodes:

Expected outcome: The AED recognizes the electrode connection, completes its self-test, and returns to a green-check ready condition.

ZOLL’s setup procedure instructs the technician to connect the electrode cable, verify the appropriate pad announcement, power the unit off, wait two minutes, and confirm the green readiness check without beeping.

If the green check appears and no warning tone is present, return the AED to service according to facility policy and stop.

9. Evaluate a Red “X” or Warning Tone

If the AED displays a red “X” or beeps after electrode replacement:

Do not repeatedly cycle or test the device after the condition is confirmed.

Expected outcome: The AED returns to a green check, or the failure is confirmed for escalation.

ZOLL recommends checking the electrode cable and performing a manual test when the AED Plus shows a red “X” or beeps. If the unit continues to fail, it is to be removed from service.

10. Check Storage and Inventory Conditions

Determine whether the electrode damage or early replacement was associated with:

Correct the external storage or inventory problem before installing additional supplies.

Expected outcome: The replacement package is protected from the condition that damaged or prematurely aged the previous electrodes.

ZOLL cautions that storage outside the recommended environmental conditions can damage electrode pads or reduce their useful life.

If the Problem Persists

If a new, compatible, sealed, unexpired electrode package is securely connected but the AED Plus continues to:

then the common external causes have been ruled out and the problem is likely within the AED connector, detection circuit, or another internal component.

The device should be:

Do not open the AED or attempt connector or board-level repair unless authorized by the manufacturer and facility policy. Knowing when to stop is proper troubleshooting.

Clinical Use Tip

Never troubleshoot questionable electrodes on an active patient when another verified AED or electrode set is available. Move care to functional equipment first, then evaluate the package and AED in a safe, controlled area.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the AED Plus CPR-D-padz package was opened and the device was no longer considered rescue ready."

Cause

What was observed during troubleshooting.

Example:
"Inspection found the adult electrode pouch partially unsealed with the cable intact, making the disposable electrodes unsuitable for continued service."

Resolution

What action was taken.

Example:
"Replaced the CPR-D-padz with a compatible sealed package within expiration, completed the AED Plus check-out test, and verified the green status check with no warning tone."

Helpful Details to Include (If Known)

Final Thought

Electrode readiness is essential to reliable AED therapy. Begin with patient safety, confirm compatibility and package integrity, replace questionable disposable supplies, verify the AED’s readiness indication, and escalate persistent failures. Accurate CCR documentation also supports inventory control and future readiness reviews.

That is successful troubleshooting.
