I have not been trained on the hands only method. Does it include clearing the airway/determining that it is clear? Does it even include checking to see if someone is not just taking a nap?
If does not, and the airway is not clear, how does air get in by the hands only method? Osmosis? I am not a certified instructor but in the past I have shown a lot of scouts how to do the old method. I can only hope that if I ever need it, someone will use the old method.
I carry a barrier around with me and if I ever need to do CPR I intend to use the old method. Although maybe instead of 15 compressions an 2 breaths I will do 30 and 2.
