But as well as this, there needs to be a bigger effort made to have automatic defibrillators widely available. They're relatively reliable and easy to use yet I've only ever seen them once (in a shopping mall). Drones aren't going to be all that much help indoors without huge improvements in machine vision and navigation, but all the same they might well prove to be a godsend for people in isolated areas.*
*In my experience, large public gatherings held outdoors nearly always have at least one ambulance present.
