Maybe you misunderstood the way I phrased my post? I meant that you're better off getting shocked with the AED as soon as possible opposed to focusing on CPR exclusively. And as far as the one shock equaling 2 minutes of CPR-this is what we were told in CPR class-meaning that the AED is more "efficient". This makes sense since CPR is prone to user error(and the fatiguing of the person performing the CPR) and the AEDs are pretty user friendly. Tells you where to place the pads, it determines if the patient needs a shock to begin with, it walks you through the whole process. I have the quote about the AED equaling 2 minutes of CPR, I'll look through my notes and post it.
Ok here is my back ground in CPR, for the last 10 years I have been an instructor trainer for the AHA. That means that I teach people how to teach you. If any of the instructors have questions they come to me. And an instructor for 5 years before that. I have been certified in CPR for the last 27 years.
The AED is the only definitive way to get someone out of cardiac arrest. It is not a more efficent way to do CPR. If you remember during your class they should have talked about the survival chain.
1. early ativation of EMS, calling 911.
2. Early BLS which is starting CPR ASAP.
3. Early use of the AED
4. Early ALS, which is using cardiac drugs
If any of these don't happen the survival rate drops alot.
Basically when you do CPR all you are doing is maintaining blood flow to the heart and brain until the AED shows up, and later on drugs. It is the shock that brings them back to live NOT the CPR. But you MUST do CPR until the AED shows up otherwise the shock might be worthless as brain damage has already happened.
Aed's are the most efficent within the first 3-5 minutes after arrest. If you can get it one during that time there is a 90% chance that only one shock is needed to convert. Even after the shock the heart is still very irratible and now needs advanced cardiac drugs to "calm" it down so it won't go out again. But you can prolong this window by doing CPR.
So the take home message is activate EMS ASAP, start CPR ASAP, get an AED placed ASAP and then let the paramedics take over when they get there. Doing only CPR or only using the AED most likely will not save the person, unless the responce time by the paramedics is very good. But the national average responce time in big cities is 6 to 10 minutes, longer in rural times. And as I said above the prime time to shock is 3-5 minutes. But by doing GOOD CPR you can prolong the shock time by a couple minutes giving the person a fighting chance.
So, everyone get trained in the use of the AED and CPR. Go to the
American Heart or
Red Cross websites and find a local class. Less then 10% of the public is currently trained in CPR, it needs to be higher.
