Importance of automated external defibrillators

Saving lives: The vital role of Automated External Defibrillators (AEDs)

Few tools are as crucial in healthcare and emergency response as Automated External Defibrillators (AEDs). These life-saving devices have revolutionised the way we address sudden cardiac arrest (SCA), significantly improving survival rates. In this blog, Dr Richard Dune delves into the importance of AEDs, exploring key facts, legislation, regulations, and best practices surrounding their use.

Key facts and statistics

  • Sudden cardiac arrest claims thousands of lives each year, with survival rates often dependent on immediate intervention.
  • According to the British Heart Foundation, only one in ten people survive an out-of-hospital cardiac arrest in the UK.
  • However, when an AED is used within the first few minutes of cardiac arrest, the chance of survival can increase by up to 70%.

Key definitions

  • Automated External Defibrillator (AED) - A portable device that delivers an electric shock to the heart to restore its normal rhythm during sudden cardiac arrest.
  • Sudden Cardiac Arrest (SCA) - A condition in which the heart suddenly stops beating, leading to loss of consciousness and death if not treated promptly.

Legislation, regulations, and best practice

  • The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate first-aid equipment, which may include AEDs depending on the workplace risk assessment.
  • The Resuscitation Council (UK) provides guidelines on using AEDs, emphasising the importance of prompt CPR and defibrillation.
  • The Medicines and Healthcare Products Regulatory Agency (MHRA) regulates the sale and use of medical devices, including AEDs, to ensure their safety and effectiveness.

The importance of early defibrillation

  • Delays in defibrillation significantly decrease the chance of survival from sudden cardiac arrest.
  • AEDs are designed for easy use by bystanders, providing audible instructions to guide users through the process.

Accessibility and placement of AEDs

  • Placing AEDs in easily accessible locations, such as workplaces, schools, and public spaces, is critical for rapid response.
  • Strategic placement of AEDs can improve response times and increase the likelihood of successful resuscitation.

Training and education

  • Proper training in CPR and AED use is essential for effective response to sudden cardiac arrest.
  • Training programs, such as those offered by The Mandatory Training Group, equip individuals with the knowledge and skills to confidently use AEDs in emergencies.


  • Conduct a thorough risk assessment to determine the need for AEDs in your workplace or community.
  • Invest in AEDs and ensure they are easily accessible and well-maintained.
  • Provide comprehensive training in CPR and AED use for employees, volunteers, and community members.
