Is your defibrillator really rescue ready? Why ongoing AED maintenance could mean the difference between life and death

A defibrillator is an essential piece of life saving equipment for workplaces, schools, communities and sports clubs. It’s a huge investment and, installing an AED provides protection for people in the local vicinity should a cardiac emergency occur.

However, purchasing and installing an AED is only the first step.

Every year, thousands of defibrillators remain mounted on the walls both inside and outside workplaces, community buildings, schools, universities and sports clubs but not all of them are truly ready for use in an emergency. A flat battery, expired pads or an unnoticed fault can all mean that the device isn’t able to effectively deliver a shock when it’s needed most.

So, if you own a defibrillator, it’s important to ask yourself one question:

If someone suffered a cardiac arrest today, would our defibrillator be able to save their life?

Being truly rescue ready involves more than simply owning an AED. You also need to ensure the device is maintained, regularly checked, easy to access and fully prepared to deliver a shock when every second counts.

What is a rescue ready defibrillator?

You might have heard the phrase ‘rescue ready’ in relation to defibrillators but be unsure about what it really means.

A rescue ready defibrillator can be taken from its cabinet, switched on and relied upon instantly to deliver a potentially lifesaving shock. The battery should have sufficient charge, the electrode pads should be within their expiry date and should have successfully completed its self-tests.

Just as importantly, someone within the organisation will understand who is responsible for the device and knows when it was last inspected.

Modern AEDs are designed to be reliable and give you the ability to simply grab them and go in an emergency. They perform regular self-checks to monitor battery condition, internal electronics and operational status. These self-tests significantly reduce the likelihood of hidden faults occurring, but they do not completely remove the need for regular human inspections.

A flashing warning light, accidental damage or expired consumables are all factors that automated testing cannot resolve on its own. Someone still needs to confirm that everything is exactly as it should be and fix any problems that might have occurred during a self-test.

Why ongoing maintenance matters

A huge mistake many AED owners make is assuming they are a ‘fit it and forget it’ device. It’s easy to understand why this may be the case because modern AEDs require very little day-to-day interaction. Weeks or months can pass without the device needing any intervention.

Unfortunately, this can lead to maintenance being overlooked altogether.

Electrode pads can expire over time as the conductive gel gradually deteriorates. Batteries have a finite operational life, even if the device has never been used. Cabinets exposed to the elements can become damaged or dirty which means they’re no longer clearly visible or accessible.

None of these issues develop overnight so regular inspections are really important. Small problems identified early are usually inexpensive and straightforward to resolve. If left unnoticed for months or years, those same issues could mean the defibrillator is unavailable when someone experiences a sudden cardiac arrest.

Regular maintenance isn’t just about complying with manufacturer guidelines, it’s about ensuring that, should an emergency occur, your organisation can rely on its life-saving equipment without hesitation.

Every defibrillator needs a human touch

Every defibrillator should have someone responsible for its ongoing care. In many cases, this is referred to as an AED Guardian or Defibrillator Guardian. This isn’t a technical role or a role that requires specialist knowledge. This person will provide an oversight of the device, ensuring that routine visual inspections are carried out, maintenance records are kept up to date and replacement consumables are ordered before they expire.

Without clear ownership, the responsibility is shared and, in many cases, this means that no one is looking after the device at all.

This is one of the most common reasons maintenance tasks are missed. Staff change roles, volunteers move on, buildings are refurbished and equipment becomes forgotten because it is rarely used.

Having a nominated person within an organisation who is responsible for the AED dramatically reduces this risk and helps ensure that routine checks become part of the normal operational procedures.

The importance of routine visual inspections

Routine visual inspections only take a few minutes but can identify issues long before they become serious or more costly. Checking the status indicator on the front of the device confirms the AED has completed its internal self-tests successfully. Looking at the expiry dates on the electrode pads and battery provides reassurance that they will still be effective in an emergency. Confirming the cabinet is clean, secure and unobstructed ensures someone can access the device quickly in an emergency.

These simple checks provide peace of mind that the AED remains operational at all times. For organisations with multiple AEDs, recording these inspections in a maintenance log also provides a useful audit trail and ensures checks continue consistently throughout the year.

Is your defibrillator registered on The Circuit?

Maintaining your defibrillator is just one part of ensuring it’s rescue ready.

It’s equally as important to let emergency services know that it exists.

The Circuit is the UK’s national defibrillator network, used by all NHS ambulance services. When someone calls 999 and a nearby publicly accessible defibrillator could help before an ambulance arrives, call handlers can direct bystanders to the nearest registered device. This has transformed how community AEDs are used across the UK and has helped improve access to potentially life-saving equipment.

However, simply registering your device and forgetting about it isn’t enough.

The information held on The Circuit needs to be kept up to date throughout the lifetime of your AED. You need to keep your profile updated if the location of your AED changes, the access code is updated, the device is temporarily unavailable, or maintenance is being carried out. Accurate information ensures the ambulance service can direct members of the public to devices they can access easily and which can be relied upon in an emergency.

Reviewing your The Circuit registration is an important part of ongoing defibrillator maintenance.

How could professional maintenance help keep your AED rescue ready?

A professional defibrillator maintenance service provides you with an assessment of your entire installation. An expert will identify any issues, inspect the physical condition of the device and cabinet, check consumables, review maintenance records and provide added reassurance that your device will be able to deliver a shock in an emergency.

For businesses, schools, sports clubs and public organisations, professional maintenance helps to tick one more job off the list and ensure that your defibrillator is properly looked after.

It also provides confidence that the battery has been checked properly, consumables are still suitable for use and peace of mind that nothing has been overlooked.

When someone’s life depends on the equipment, ensuring it will function when needed is essential.

If you’d like a better understanding of why ongoing servicing is recommended for your defibrillator, our blog The importance of maintaining your AED explains how preventative maintenance helps ensure your defibrillator remains ready throughout its working life.

Rescue readiness requires ongoing maintenance

Every defibrillator is purchased along with the hope that it will never need to be used. But also with the hope that it will save a life if it’s needed.

If the device is needed when someone collapses from sudden cardiac arrest, there won’t be an opportunity to replace expired pads, order a new battery or investigate a warning light.

Maintenance and preparation are needed long before the emergency actually occurs.

Maintaining your defibrillator, keeping accurate inspection records, reviewing your registration on The Circuit and ensuring your AED is regularly checked are all relatively small tasks when compared to the potential impact they can have.

A rescue ready defibrillator means: Having the confidence that, if someone needed it today, your AED would perform exactly as intended.

New to defibrillator ownership?

If your organisation has recently purchased an AED, choosing a guardian and setting out a maintenance routine from the start will help you ensure your defibrillator is always rescue ready.

From understanding what’s included in your purchase to replacing consumables and scheduling routine inspections, establishing good habits early makes long-term ownership much simpler.
