The defibrillator drone that can beat ambulance times

A drone which could deliver a defibrillator to a person suffering from a cardiac arrest is being tested by the Karolinska Institute in Sweden.

Trial flights have the shown the drones can arrive at a destination four times faster than an ambulance.

After cardiac arrest, the chances of survival decrease by 10% for every minute that an individual goes without cardiopulmonary resuscitation (CPR) or defibrillation.
