The Vital Role of Defibrillators in Saving Lives

Automated External Defibrillator (AED) programmes are significantly enhancing survival rates for out-of-hospital cardiac arrests (OHCAs) across the UK and Ireland. With thousands of lives at stake each year, the strategic placement of AEDs and increased public awareness are proving vital in bridging the gap between collapse and critical intervention. [26]

Sudden cardiac arrest remains a major public health challenge. In the UK, there are over 30,000 to 40,000 out-of-hospital cardiac arrests annually, with fewer than one in ten people surviving. [16, 26, 31] Similarly, Ireland sees approximately 5,000 sudden cardiac arrests each year. [26] These stark figures underscore the urgent need for widespread access to AEDs and increased public confidence in their use. The Resuscitation Council UK (RCUK) and the Irish Heart Foundation consistently emphasise that early cardiopulmonary resuscitation (CPR) and defibrillation can more than double the chance of survival. [26] For every minute without CPR and defibrillation, the chance of survival decreases by up to 10%. [26]

Progress in the UK: Schemes and Statistics

The UK has seen considerable efforts to increase AED accessibility. The British Heart Foundation (BHF) reports over 120,000 defibrillators registered on The Circuit, the national defibrillator network. [26] As of July 2025, 58.6% of these were accessible 24 hours a day, seven days a week, representing a substantial increase in registered devices. [16, 26] The Department for Education, in June 2025, announced that its defibrillator programme had provided over 20,000 devices to schools in England. [17] This initiative aims to equip all schools with at least one AED by the end of the academic year 2022/2023. [3]

Despite this progress, AEDs are currently used in a minority of cases. In England, public access defibrillators were used in only 7.9% of OHCAs in 2024. [15, 26] Research in the East of England indicated that while AEDs were available within 500m of a cardiac arrest in 79% of cases, they were only used in 10% of those incidents. [26] This highlights a significant opportunity for improvement through enhanced awareness and accessibility.

While there is no legal requirement for most workplaces in the UK to have an AED, updated British Standards (BS 8599-1:2019+A1:2026) now specify that an AED should be available in workplaces with five or more people present, and accessible within two minutes (one minute to locate, one minute to prepare). [3, 11] This is considered best practice for demonstrating compliance with Health and Safety Executive (HSE) law. [3] The HSE itself states that while AEDs are not mandatory, if an employer decides to provide one, it falls under the Provision and Use of Workplace Equipment Regulations 1998 (PUWER), requiring information and instructions for its use. [13]

Ireland's Initiatives and Challenges

In Ireland, the Health and Safety Authority (HSA) released updated 'Guidelines on First-Aid at Places of Work' in December 2024. These guidelines include updated information on the use and maintenance of AEDs, highlighting their importance in increasing survival chances during sudden cardiac arrest. [18] While Irish employers are legally required to assess risks and put appropriate first aid measures in place, including determining the necessary first aid facilities and equipment, there is no specific legal mandate for all businesses to have an AED. [18, 21] However, it is highly recommended and considered good practice by the HSA, especially where a first aid responder is present. [21, 22]

Ireland's Out-of-Hospital Cardiac Arrest Register (OHCAR) reported that in 2024, 232 individuals survived to leave hospital alive out of 2,885 cases where resuscitation was attempted, representing an 8.0% survival rate. [23, 37] This marks an increase compared to previous years. [37] Bystander CPR was attempted in 84% of cardiac arrests in 2024 not witnessed by emergency medical services. [23] Attempted defibrillation before the arrival of emergency medical services increased to 12% of all patients. [23] The National Out-of-Hospital Cardiac Arrest Strategy (2019) aims for Ireland to achieve survival rates comparable to best-performing European neighbours, consistently around 10%. [37]

A key recommendation of the OHCA Strategy is the development of a National AED Registry mapped to the National Ambulance Service (NAS) dispatch system, and a supporting application for dispatching first responders. [37] Work is at an advanced stage, with a Community First Responder (CFR) App currently being trialled. [37] Ireland already has a network of over 330 CFR schemes involving approximately 4,500 volunteers. [37] These volunteers provide critical, life-saving support in the minutes before an emergency ambulance arrives, particularly in rural areas where response times may be longer. [36]

The future of defibrillator accessibility in both the UK and Ireland hinges on continued efforts to address disparities in access, enhance public confidence in using AEDs, and ensure all devices are registered and readily locatable by emergency services. [36]
