Drone helps save cardiac arrest patient in Sweden

An autonomous drone has helped to save the life of a 71-year-old man who was suffering a cardiac arrest.

The drone delivered a defibrillator to a doctor helping the man, who became ill while shovelling snow outside his house in Trollhattan, Sweden.

The man, who didn't wish to be named, told the BBC it was "fantastic" that it arrived so quickly.

The company behind the drone says it meant that defibrillation could begin before the arrival of an ambulance.

Everdrone says it took just over three minutes from the alarm being raised until the Automated External Defibrillator (AED) was delivered.
