For anyone with an emergency medical background or even basic BLS training, the life-saving acronym has always been the mantra of A-B-C - that is, Airway, Breathing and Circulation - in THAT order. This has been the protocol for a very long time.

Honestly, as with any recent development or new insight, I've never been an "early adopter" so to speak, but a conservative, more so when lives are at stake. I feel the need to ask those more knowledgeable on this one.

Just a reminder again though, as I mentioned previously in the Dislcaimer reference post above: you can't learn CPR and the basics of First Aid simply from the web alone. Go and get trained properly by a competent instructor at your nearest Red Cross!
