Why AEDs Crucial in Cardiac Arrest Emergencies: How to Operate AED
Sudden cardiac arrest is one of the leading causes of death around the world, and the window of opportunity to save a life is incredibly small. When someone’s heart stops, every minute counts. This is where an Automated External Defibrillator (AED) combined with cardiopulmonary resuscitation becomes essential for effective basic life support. AEDs are life-saving devices that are accessible, easy to use, and designed to help a non-medical bystander step in during a cardiac emergency.
At First Aid Course Experts, we believe in equipping everyday people with the skills they need to save lives. Through comprehensive first aid & CPR training, you can learn how to respond confidently in emergencies. In this article, we’ll discuss why AEDs are crucial in cardiac arrest situations and provide detailed instructions on how to use them safely.
Proper training is essential to effectively use an AED during cardiac emergencies, as immediate response can significantly improve survival rates.

These courses provide hands-on experience and detailed guidance on AED operation, making them a valuable resource for individuals and organizations aiming to enhance their emergency preparedness.
What Is an Automated External Defibrillator (AED) and How Does It Work?
Understanding the Role of AEDs in Treating Cardiac Arrest
An Automated External Defibrillator (AED) is a portable electronic device designed to diagnose and treat life-threatening cardiac arrhythmias, particularly ventricular fibrillation and pulseless ventricular tachycardia. When the heart stops beating effectively due to these irregular rhythms, the AED delivers an electric shock to restore a normal heart rhythm.
Unlike the defibrillators used in hospitals, AEDs are designed for use by laypeople in everyday environments. These devices provide simple, clear, and automated instructions to guide you through the process. AEDs are becoming increasingly common in public places like airports, schools, shopping centres, and workplaces because they dramatically increase the chances of survival when used promptly in a cardiac emergency.
How Does an AED Help the Heart Regain a Normal Rhythm?
Often when someone suffers from cardiac arrest, the electrical signals in the heart malfunction. Instead of the heart beating regularly and pumping blood, it quivers ineffectively, a condition known as ventricular fibrillation. The AED works by analysing the person’s heart rhythm and, if necessary, delivering a shock that can reset the heart’s electrical system and restore a normal, effective rhythm.
The AEDs design allows anyone to use it, whether they are trained or not. However, pairing AED use with CPR training certification ensures that users are well-prepared to handle emergencies quickly and efficiently, potentially saving more lives.
Why Time Matters: AEDs and Cardiac Arrest Survival Rates
The Importance of Early Defibrillation in Sudden Cardiac Arrest
When someone experiences sudden cardiac arrest, their survival chances decrease by 7-10% for every minute that passes without defibrillation. After 10 minutes, the likelihood of survival is near zero. Early defibrillation, ideally within the first 3 to 5 minutes, is key to saving lives. For this reason, having AEDs readily available in public spaces and training individuals to use them is vital.
Research by health authorities such as the American Heart Association, has shown that survival rates can more than double when AEDs are used before emergency medical professionals arrive. In some cases, the use of AEDs has increased survival rates from 5% to over 50%. This staggering improvement highlights the importance of timely AED access in the event of sudden cardiac arrest.
How AEDs Make a Difference in Public Spaces and Workplaces
The growing presence of AEDs in public and workplace settings is a direct response to the urgent need for early defibrillation. By strategically placing these devices in high-traffic areas, employers and organisations can create safer environments. Ensuring that staff are trained in both first aid and CPR not only makes workplaces compliant with safety regulations but also empowers individuals to act confidently in emergencies.

Through accredited CPR courses, businesses can provide employees with the knowledge to recognise cardiac arrest symptoms, perform CPR, and operate AEDs correctly to deliver the shock that will save a life. Whether you’re working in an office, a school, or a gym, knowing how to use an AED can be the critical difference.
How to Use an AED: A Step-by-Step Guide for Safe Operation
Key Steps for Using an Automatic External Defibrillator during a Cardiac Emergency
AEDs are designed to be user-friendly, but following the right steps is critical to ensuring safe and effective use. Here is a step-by-step guide to help you use an AED during a cardiac emergency:
- Call for help: Immediately call emergency services (000 in Australia) or ask someone else to do so while you attend to the person in need.
- Check responsiveness and breathing: Ensure the person is unconscious and not breathing or not breathing normally (gasping doesn’t count as normal breathing).
- Start CPR: Begin chest compressions while you retrieve the AED. This ensures that blood circulation continues until the AED is ready.
- Turn on the AED: Once you have the AED, open it and turn it on. The device will provide clear audio and visual prompts.
- Attach the pads: Place the electrode pads on the person’s bare chest, one on the upper right side and the other on the lower left side of their chest.
- Let the AED analyse: Stand clear and allow the AED to analyse the person’s heart rhythm.
- Follow AED instructions: If a shock is advised, ensure no one is touching the person and press the “shock” button. If no shock is advised, continue CPR until emergency medical professionals arrive.
- Continue until help arrives: After the shock, or if no shock is needed, continue with CPR and follow any further prompts from the AED.
These steps may seem overwhelming at first, but with proper first aid & CPR training, anyone can become confident in using an AED effectively.
Common Mistakes to Avoid When Operating an AED
While AEDs are designed to be easy to use, some common mistakes can compromise their effectiveness. Avoid these errors:
- Not calling emergency services: Always call for professional help, even if you’re using an AED.
- Touching the person during analysis or shock: This can interfere with the AED’s rhythm assessment or deliver a shock to you.
- Skipping CPR: AEDs are highly effective, but CPR should be performed until the AED is ready or between shocks to maintain blood flow.
Where to Find AEDs: Public and Workplace Availability
How to Identify AED Locations in Public Spaces
In many countries, AEDs are required in public spaces like airports, shopping malls, gyms, and schools. AED locations are often marked by a green and white sign featuring a heart with a lightning bolt symbol. Familiarising yourself with these signs and taking note of AED locations in your workplace and community can be lifesaving.
When entering any public space, it’s a good habit to locate the nearest AED. In an emergency, knowing where the AED is can save valuable time.
Should Your Workplace or Organisation Have an AED?
In Australia, many workplaces are now required to have AEDs readily available. However, even in places where it’s not legally mandated, having an AED on-site is a smart decision. AEDs are small, affordable, and can be used by anyone. Ensuring that your staff is trained to use these devices through first aid courses ensures your workplace is prepared for emergencies.
Workplaces with high foot traffic, or those with employees at greater risk for cardiac events, should make AED access a priority. Having an AED not only saves lives but also demonstrates a commitment to employee safety and wellbeing.
