I'm CPR trained with many recerts over the years. AEDs do everything for you, you just have to apply the pads in the correct spot (every AED has a visual diagram) and press the big button. They're intentionally designed to be easy to use now.

Also, get CPR certified. Takes an hour or two at most and you could save a life.

Caveat that it won't shock anyone they don't need to as long as that person isn't conscious or moving...

The AED doesn't shock people who are in asystole (flatline), contrary to popular myth. The point of shocking isn't to start the heart, it's "have you tried shutting it off and turning it back on again?" It shocks 2 rhythms, ventricular tachycardia (a type of very fast heart rate) and ventricular fibrillation (where the bottom part of your heart quivers but doesn't pump). It's possible to be alive and conscious in V tach, you can be pulseless and "dead" with V tach and you won't have a pulse with V fib. So if you apply it to someone conscious, there's a chance they could be in V tach and it will recognize that and shock them, killing them. It can also recognize movement as a shockable rhythm and deliver a shock improperly.

None of this should scare anyone from using an AED! If you have someone who isn't conscious, isn't breathing, and doesn't have a pulse or you don't know how to check for one, you can use an AED! Just don't put one on someone who is awake and having chest pain "just in case" and if you need to move someone that has an AED applied, don't do it while the AED says it is analyzing (you will know, it verbally says so and tells you to stop touching the patient!)

Go learn CPR! It is not hard, and you can save a life. Remember, if someone needs CPR you can't screw it up! They can't get any more dead, but you can make them better!

• not a CPR instructor, but I do work in EMS :)

Completely agreed! I've used a few in practice sessions and they are quite easy. The one thing to be aware of is that you do need to get the sticky electrodes in the right place. There is a simple diagram showing where they go. But you will need to get under their shirt and bra to place them, so make sure you're not pulling down a strangers clothes for the wrong reasons.

Depends where you live. Pretty sure here you need a code to open it which you can get while calling for an ambulance and they direct you to the nearest one.

OSM mapping can be very fun, I started doing it more than half my life ago. :D Not just defibrillators, but lots of other things too!

Is that like a fork of StreetComplete (or the other way around)? My problem with street complete is that it decides priorities for you in terms of what info to ask you for. Like I dont care much about reporting road surfaces and lane lines, but I'd really like to contribute to mapping of hiking/biking trails, and things like water sources. I know you can do that kind of thing via web interfaces, but I like the way street complete makes it easy in an app.
