What to Do After Using an AED

Once an AED (Automated External Defibrillator) has been used, it must be properly checked, restocked, and returned to service. An AED that has been deployed but not reset may be unavailable when it is needed again.

Taking the AED Out of Service

After use, it is common for an AED to be temporarily out of service. This is usually because:

• The electrode pads have been used
• The battery may be partially depleted
• The AED preparation kit items have been used

If your AED is registered on The Circuit, log in and mark the unit as unavailable until it has been fully restocked.

Replacement pads and batteries are available quickly for most AED brands. If you require spares or batteries, contact your supplier so these can be arranged promptly.

Initial Inspection of the AED

Before restocking, visually inspect the AED:

• Check the casing for any signs of damage
• Ensure there is no visible damage to connectors or cables
• Confirm the unit still powers on and appears to function normally

In most cases, the AED itself will be undamaged and fully operational.

Removing and Replacing AED Pads

Once AED pads have been used, they must be discarded.

• Unplug and remove the used pads
• Dispose of them appropriately
• Fit a new, unused set of pads

It is essential to order the correct pads for your specific AED. Pads are not interchangeable between brands or models, as the connectors differ.

Always check:

• The manufacturer
• The model number
• The pad connector type

Replacing the Battery

Although an AED battery may still have some charge after use, best practice is to replace the battery after every deployment.

This ensures:

• Maximum battery life for future emergencies
• Full confidence the AED will deliver therapy if required

An AED may still work with a partially used battery, but replacing it guarantees the unit is fully ready for the next emergency.

Restocking the AED Prep Kit

The AED prep kit is often overlooked. These kits usually contain:

• Gloves
• A razor
• Wipes or gauze

If the AED has been used, these items should be replaced. Order a new prep kit at the same time as replacement pads and batteries.

Downloading Event Data

Most AEDs store event and ECG data. Depending on the model, this data may be downloaded via:

• Bluetooth
• Wi-Fi
• USB
• SD card

Download this data as soon as possible. AEDs have limited storage capacity, and data may be overwritten if the unit is used again.

There will always be sufficient battery life remaining to download the data safely.

Returning the AED to Service

Once the AED has been fully restocked:

• Fit the new pads and battery
• Carry out a quick function check
• Update The Circuit to confirm the AED is available again

Switch the unit on briefly to confirm it is working, then turn it off and return it to its usual location.

If the AED Is Still Out of Service

If the AED is housed in a public cabinet and cannot yet be returned to service:

• Ensure it is removed from the 999 network
• Place a clear sign on the cabinet stating the AED is currently unavailable

This prevents valuable time being wasted searching for an AED that is not ready for use.

Key Points to Remember

• Used pads must always be replaced
• Replace the battery after every use
• Restock the AED prep kit
• Download event data promptly
• Update The Circuit once the AED is ready
• Clearly signpost any AED that is out of service

Correctly restoring an AED after use ensures it is ready to save the next life.
