When to Use a Defibrillator: Understanding Sudden Cardiac Arrest (SCA)

Recognising the right moment to use a defibrillator is crucial for saving lives during sudden cardiac arrest (SCA). SCA occurs when the heart abruptly stops functioning correctly, leading to a rapid loss of consciousness and the absence of a pulse. To effectively manage this critical situation, it is essential to understand how and when to use a defibrillator.

What is Sudden Cardiac Arrest (SCA)?

Sudden cardiac arrest is a severe medical emergency where the heart stops pumping blood efficiently due to an electrical malfunction. Unlike a heart attack, which typically results from a blockage in the arteries, SCA can happen without warning and is often fatal within minutes if not treated immediately. Various underlying conditions, such as coronary artery disease or arrhythmias, can trigger SCA. For a more detailed explanation, visit our page on Sudden Cardiac Arrest or view the NHS Sudden Cardiac Arrest page.

The Importance of Immediate Defibrillation

Given the urgency of SCA, time becomes a critical factor. Every second counts. A defibrillator, which delivers a controlled electric shock to the heart, aims to restore a normal rhythm. It is important to note that each minute without defibrillation decreases the chances of survival by 7-10%. Therefore, using a defibrillator promptly is not just advisable—it is vital. To understand more about how defibrillators work, check out our Defibrillator Guide or visit the British Heart Foundation for additional insights.

When and How to Use a Defibrillator

If you encounter someone who is unresponsive and not breathing normally, it is imperative to act swiftly and follow these crucial steps:

  1. Call Emergency Services: First and foremost, dial 999 to ensure that professional medical assistance is on its way. While waiting for them, every action you take could be life-saving.
  2. Start CPR Immediately: Immediately begin CPR. Place the heel of your hand in the centre of the person’s chest, place your other hand on top, and push down hard and fast—aim for 100-120 compressions per minute. This action helps maintain blood flow to vital organs while you prepare to use the defibrillator. For a detailed guide on performing CPR, visit the NHS CPR Instruction Page.
  3. Retrieve and Use a Defibrillator: If a defibrillator is available, retrieve it quickly. Modern defibrillators are designed to be user-friendly, providing clear voice instructions. Once you turn it on, follow the prompts to attach the adhesive pads to the person’s chest. The device will analyse the heart’s rhythm and guide you on whether to deliver a shock.

  4. Deliver the Shock: If the defibrillator advises a shock, ensure everyone is clear of the person before pressing the shock button. The shock is intended to reset the heart’s rhythm, offering a chance for it to resume normal functioning.
  5. Continue CPR: Immediately resume CPR after delivering the shock and continue until emergency responders arrive. If the defibrillator instructs further shocks, follow its guidance. The continuity of care is crucial in improving the person’s survival chances.
