Defibrillator drones could save lives before ambulance arrives

Drones aren't just good for getting your shopping in an instant – by carrying defibrillators they could prove to be life-saving if your heart stops beating. Only around one in ten people survives a cardiac arrest outside hospital. Having a bystander perform chest compressions improves your chances, but a shock from a defibrillator must be applied quickly to restart the heart. Every minute without CPR and defibrillation reduces someone's chance of survival by 10 per cent. Defibrillators are designed to give spoken instructions so that anyone can use them, and many are available in public places.
