Note how the data gets contaminated here.

CPR is simply buying time, at best it can delay death in the hope the doctors can do something about whatever caused the heart to quit. Usually they can't.

AED is different. Despite what Hollywood would have you believe the shocker does not start your heart and it is never used on a stopped heart. Shocking is about the heart beating ineffectively. It has a chance of actually treating the problem, not merely buying time. If the heart is stopped the AED just sits there and says continue CPR. And people blame it for being defective.
