This is wrong, CPR almost never brings people back. What CPR does is provide minimal bloodflow and oxygenation until electricity can be used to get the heart beating properly again. By doing this, you extend the window during which an AED (or other defibrilator) can be used successfully and hopefully reduce brain damage in the event of that success. Indeed, if you have an AED, delaying its use to provide CPR is bad.
