Call 15, perform chest compressions, defibrillate: These are the three critical actions for cardiac arrest—a sudden cardiac event that can strike anywhere. In France alone, it claims 40,000–50,000 lives yearly, or about 130 daily.
In most cases, cardiac arrest stems from a rhythm disorder called ventricular fibrillation, where the heart's electrical activity becomes chaotic. This often follows a coronary blockage, known as acute coronary syndrome or heart attack. The heart races ineffectively, failing to pump blood to vital organs, especially the brain. This triggers unconsciousness, respiratory arrest, and death within minutes if untreated.
Imagine walking down the street when someone collapses ahead. Rush over: if they're unconscious, unresponsive to shouts like "Can you hear me?" or "Squeeze my hand," not reacting, and not breathing normally (or only gasping)—the agonal breaths signaling imminent death—it's cardiac arrest. Act with these three citizen lifesaver steps!
Keep your cool and enlist bystanders—you shouldn't handle this alone. Everyone has a mobile phone: dial 15 for SAMU. Expect these four questions:
1) What happened?
2) Where are you and the victim? (Repeat the exact location.)
3) What have you done so far?
4) Do you know CPR?
Stay on the line—the SAMU dispatcher can guide you through compressions if needed and dispatches the SMUR team. They'll instruct you when to hang up.
During sudden cardiac arrest, arterial blood remains oxygenated—the issue is circulation. The heart pump has failed, starving the brain. Without flow, irreversible brain damage sets in after 6 minutes. Priority: restart blood flow.
Lay the victim on their back, bare the chest, kneel beside them. Stack hands, arms straight, at chest center (between nipples). Compress at 100+ per minute (2 per second), 5–6 cm deep, allowing full chest recoil. Do continuously in 30-compression cycles, but rotate rescuers every 2 minutes—no one sustains it alone.
After 5–6 minutes, oxygen depletes; trained rescuers add ventilations (30:2 ratio). Untrained? Skip mouth-to-mouth—compressions alone provide some ventilation. Continue until SAMU arrives or the victim revives.
Since May 2007, French law (DEA Decree 2007) empowers anyone to use automated external defibrillators (AEDs).
Ventricular fibrillation requires an electric shock to restore rhythm, as shown in educational videos from the French Federation of Cardiology.
AEDs are in high-traffic spots (stations, malls, stadiums—where 500 athletes die yearly from exertion) and remote areas. Apps locate public AEDs in France.
Ask bystanders for the nearest AED or check with SAMU. AEDs are user-friendly: open, power on, apply electrodes per diagram, follow voice prompts. Fully automatic models shock if needed; semi-automatic ones prompt you. Zero risk to rescuers—it analyzes rhythm, clears bystanders, and advises.
Time is everything: Pre-2007, fear of liability meant waiting 10–30 minutes for SAMU, with just 2–3% survival. Acting boosts odds dramatically. Never do nothing! Remember: Call 15, compress, defibrillate! Get trained—free Initiations aux Premiers Secours (IPS) take hours.
