Not sure what the situation is in the US, but I've taken 3-4 first aid courses in my life (it's compulsory to get a driver's license where I live). Every time, they told us that CPR survival rates were abysmal if we aren't also using an AED. IIRC, with an AED the survival rate goes up significantly -- though this article states that in-hospital survival rates are only at 17%, which indicates it's not all that great with AED, either.
