I think small flying vehicles are cool and this is a good use for them, but if this is true, are there other ways to get more people equipped with some of these lifesaving skills at possibly lower marginal cost? CPR training? More AEDs? Some more kinds of injectors that can be used by people with minimal training? Maybe there are other devices on the model of the AED that could administer other kinds of potentially-dangerous treatments?

There's also the ability to stick AEDs on drones, which relies on the member of the public reporting the heart attack to use it, but can make them available to that person much more quickly than instructions about where to find the nearest publicly-accessible AED.

You can obviously also have a lot more defibrillator drones available across a city than jetpack-equipped paramedics. I've seen it as a concept, not sure how many are in use and what their success rates have been.
