JUST AMAZING! A Dutch-based engineering student has revealed a prototype `Ambulance Drone`... a flying defibrillator! It can fly at speeds up to 100 kms per hour and tracks emergency mobile calls using GPS to navigate. If an ambulance took 10 minutes to reach a cardiac arrest patient, the chance of survival is only 8%. But the drone can get a defibrillator to a patient inside a 12 km sq zone within a minute, increasing the chance of survival to 80%.
