Defibrillator guardianship explained: Who is responsible for looking after an AED?

It is recommended that, if your organisation has an Automated External Defibrillator (AED), that you appoint a dedicated Defibrillator Guardian. This is a dedicated person who should be responsible for ensuring the device is always rescue ready by replacing consumables, performing regular checks and maintaining records.

Purchasing a defibrillator is a great first step towards ensuring that, if someone suffers from cardiac arrest in the immediate vicinity, life-saving equipment is quickly on hand. But it’s not the final step.

When purchasing a defibrillator, there can be excitement around choosing the right model and installing it. However, once it’s installed, it can quickly become forgotten. Over time, the device becomes neglected and may fail to work in a real emergency.

In this blog, we’ll explain what a Defibrillator Guardian does, why you should appoint one and how assigning ownership can help ensure your AED is rescue ready in an emergency.

What is a Defibrillator Guardian?

A Defibrillator Guardian is the person assigned to oversee the ongoing maintenance and management of an AED.

This is a role recommended when you buy a defibrillator to ensure someone within your organisation has ownership of the processes required to keep your AED fully rescue ready and available in an emergency.

It’s similar to a fire marshal or first aid coordinator. They ensure inspections happen, records are maintained and equipment is available when needed.

Depending on your organisation, this person could be:

A health and safety manager
A facilities manager
A site manager
A school business manager
A parish clerk
A practice manager
A workplace first aider
A volunteer responsible for community facilities

It doesn’t matter who is appointed, what matters is that that person and everyone else in the organisation knows who is responsible for looking after the device.

Why should you appoint a Defibrillator Guardian?

Imagine if someone, an employee, visitor or passerby, suffers a sudden cardiac arrest in or around the location of your AED. The defibrillator won’t work because something has failed. Time passes without anyone delivering a shock to the patient and the emergency quickly becomes fatal.

And all because the responsibility for your defibrillator wasn’t clearly assigned so no-one knows whether it’s been checked or not or if there’s a problem.

Appointing a Defibrillator Guardian creates accountability within your organisation. Everyone knows someone is looking after the AED, keeping maintenance records up to date, replacing consumables and arranging professional serving when required.

This role removes uncertainty and significantly reduces the risk of an AED that won’t deliver a shock in an emergency.

What does a Defibrillator Guardian actually do?

All a Defibrillator Guardian has to do is coordinate the ongoing management of the AED and ensure routine checks are carried out.

Typical responsibilities include:

Arranging or carrying out routine visual inspections
Monitoring pad and battery expiry dates
Keeping maintenance records up to date
Arrange professional servicing when appropriate
Review signage and accessibility
Update organisational records after AED has been used

Many of these responsibilities only take a few minutes each month. However, when coordinated consistently, they provide confidence that the defibrillator will be ready if someone experiences a sudden cardiac arrest.

If you’re unsure of exactly what should be inspected during routine checks, our guide to The Importance of Maintaining your AED explains the process in more detail.

They don’t have to do everything themselves

One of the biggest misconceptions about Defibrillator Guardianship is that the Guardian must personally complete every single inspection and maintenance task or be specially trained.

But the role is much broader than this.

A Guardian is responsible for ensuring checks are made and inspections and maintenance happen. They don’t always have to personally carry them out.

The Guardian role is designed to ensure that someone is looking after the device and knows whether it’s rescue ready or whether there’s a problem that needs fixing. They don’t have to be the person to fix the issue.

The Defibrillator Guardian should know:

Where the AED is located
Any access codes
How often inspections are completed
Where maintenance records are stored
When the battery and pads are due for replacement
Who to contact if any issues arise

This can work particularly well in larger organisations where responsibilities are shared across a number of departments. The important part is that one person is accountable for ensuring all tasks are completed and that the AED can be relied upon to deliver a life-saving shock in an emergency.

Without a central point of ownership, maintenance programmes can easily be forgotten. Having a Defibrillator Guardian provides continuity, ensuring the same standard are maintained regardless of staff changes, annual leave or organisational growth.

Should you arrange for professional defibrillator servicing?

Routine visual inspections of the device are one of the most important roles for a Defibrillator Guardian.

However, you might choose to add an added layer of reassurance with professional servicing. A professional service may be able to identify issues that might not be immediately obvious during visual inspections or to someone who is untrained.

Whether or not you organise professional servicing depends on your organisation, the number of AEDs you manage and the resources available internally.

Supporting a Public Access Defibrillator

If your defibrillator is available for public use, the Guardian’s responsibilities go beyond routine inspections.

Your AED should be registered on The Circuit , the UK’s national defibrillator network and part of the Guardian’s role should be to keep this information up-to-date. This includes confirming accessibility details and updating the system if the defibrillator is temporarily unavailable following an emergency.

During a 999 call, ambulance service call handlers use The Circuit to direct bystanders to the nearest available AED. Keeping your information current ensures rescuers are directed to a defibrillator that is fully functional.

Our guide to registering your defibrillator on The Circuit covers this in more detail.

Frequently asked questions

Does every organisation need a Defibrillator Guardian?

These is no legal requirement to appoint a Defibrillator Guardian but, it is recommended that any organisation with an AED should appoint one person responsible for coordinating inspections and ongoing maintenance. This helps ensure your device is rescue ready when it’s needed.

Does a Defibrillator Guardian need medical training?

No, your Defibrillator Guardian doesn’t need to be a healthcare professional or have any other qualifications. Their role is to oversee the management of the device rather than repair it or provide medical treatment.

Can more than one person share the responsibility?

While several people can assist with inspections and maintenance, having one dedicate Guardian who is accountable for ensuring all tasks are carried out is recommended to prevent maintenance from slipping through the cracks.

How often should a Defibrillator Guardian check the AED?

Routine visual inspections should be carried out in line with the manufacturer’s recommendations and your organisation’s maintenance schedule. However, many organisations choose to complete checks monthly alongside other inspections.

Is a Defibrillator Guardian responsible for replacing pads and batteries?

The Guardian should ensure replacement consumables are ordered and fitted before they expire. This responsibility should be carried out internally or through a professional servicing provider.
