Cardiac Arrest and AED Go Hand in Hand: The First is the Emergency, The Second is the Tool That More Than Any Other Can Change the Outcome If Used Immediately

What Cardiac Arrest Really Is It's not a heart attack. In a heart attack, the heart is blocked by an obstructed artery, but it's still beating. In cardiac arrest, the heart suddenly stops pumping: the person loses consciousness, isn't breathing normally, and doesn't respond. Without circulation, permanent brain damage begins after 3-5 minutes. In Europe, it happens approximately 400,000 times a year outside the hospital, and the average survival rate is only around 7.5% — but it rises to 20-25% where citizens are trained and AEDs are widespread.

Why the AED is No Longer "For Doctors" The new European Resuscitation Council 2025 Guidelines clearly state: the automated external defibrillator is not an optional extra reserved for professionals; everyone should initiate its use as soon as possible, within their capabilities.  In Italy, Law 116/2021 and the Prime Ministerial Decree of October 23, 2024, created a five-year program to place AEDs in public places, with priority for schools, universities, train stations, airports, sports facilities, and transport vehicles, with the aim of ensuring defibrillation within 3-5 minutes of arrest. Defibrillation within 3 minutes of a witnessed arrest can increase survival to over 50%. 

The law protects those who intervene in good faith: you don't need to be a healthcare professional; you need to follow the AED's voice instructions. The Chain of Survival, updated 2025 1. Prevention and recognition – call 112 immediately (single emergency number in Sicily, it connects you to 118) if you see unusual signs. 2. Alert and immediate CPR – deep chest compressions at least 5 cm, not exceeding 6 cm, at 100-120 per minute, with minimal interruptions.  3. Early defibrillation – send someone to get the nearest AED. 4. Advanced care and recovery – after the return of a heartbeat, the path of rehabilitation and psychological support begins, which the new guidelines prioritize. 

How to Use an AED, Step by Step The AED speaks for itself. You don't have to interpret anything. • Safety: check the environment, do not touch the victim if there is danger. • Call: 112, put on speakerphone. Say "cardiac arrest, bring AED." • Start CPR: 30 compressions in the center of the chest, then 2 rescue breaths if you know how, otherwise only continuous compressions. • Turn on the AED: open the lid, press ON. Follow the voice. • Bare the chest: dry it if wet, remove patches. If very hairy, use the razor in the bag. • Apply the pads: one below the right collarbone, the other on the left side below the armpit, as in the diagram. • Analyze: the AED says "do not touch." No one should touch the victim. • Shock: if indicated, the AED charges and says "press the button." Make sure everyone is clear, then press. • Immediately resume CPR: 2 minutes of compressions, then the AED reanalyzes. Continue until emergency services arrive or until the person moves. Do not remove the pads, even if the person recovers.
