From what I remember you only had 5-6% cognitive function to begin with so how could they tell? (I was always jealous because yours was four or five percent more than mine.)
I had learned CPR back in the 80's and saved two lives with it but had not used it in many years, when I joined the Firehouse down the road as a part of the then "Women's" auxiliary I learned that they have changed how they do it now, when I learned it they had you arch the next and lift the chin but that is a major NO-NO now. I was set to go learn it the new way but ended up with a case of the back door trots so now I am waiting for them to offer it again. I am not honestly sure how much of it I can do physically anymore, but I figure I can talk a able bodied person through it if I know the proper technique.
I am glad to hear you made it.
