Went to a certification for CPR yesterday. Cardiac problem is one of the leading causes of death in the US. I figured that I should know some things about it.
Learned how to do the Heimlich maneuver as well as CPR. Also learned that there are now disposable mouth shields in case you don't want to have mouth to mouth contact with someone.
The teacher posed an interesting question. What if you see a stranger pass out and you don't have one of your face shield / mouth shield. What do you do? In the old days of the 1970's, they used to just put mouth over mouth. But with the coming of AIDS and hepatitis, those days are now over.
The answer is that you can give them chest compression until someone comes along. Hmm, maybe I would let someone else better trained than me to handle that. But it does pose you a tickle, doesn't it? You essentially have to measure your life against their life.
I also learned that there are now new electronic defibrillation devices that one can use in the event of a heart attack. Apparently, it is better to defibrillate earlier than later.
