>>Here's one scenario. I have been injured but am conscious. I give the instructions to the only person in the situation with me right before I quit breathing.

I have to agree with TackDriver. The chance of you having advance knowledge that your heart is about to stop beating is almost nil. The time the other person wastes trying to read and understand the card would be much better spent calling 911.

If they position their hands incorrectly, they will break off the Xiphoid Process, which is a small piece of cartilage at the base of the ribcage (where the two sets of ribs meet). This can cause serious, potentially fatal internal damage. Couple this with the fact that you may not, in fact, be in any danger and you’ve just turned a simple fainting spell into a lacerated liver, internal bleeding, long-term complications, and possibly death.

Most of my students have difficulty positioning their hands correctly – this includes people who were previously CPR trained, after they’ve watched an instructional video and I have demonstrated the proper technique in person.
I’d think twice.

>>2nd Scenario. There's a huge wreck and hundreds of bodies which need attention. While i'm giving CPR to victims I can give the instructions to a good samaritan and allow them to help others as well.

Proper response to such an incident, if there are not enough first aiders to treat all the injured, is to assume anyone without a pulse is dead and move on. Harsh, but while you’re dicking around trying to teach Joe Hysterical Bystander some complicated life-saving skills, 6 people that you could have saved have gone into shock and died. I suggest you re-read your First Aid manual on MCIs.

>>Although I have been CPR trained for over a decade, have retrained, and performed this task to save a life I think a good set of instructions could help a good samaritan who has never done it before. The instructions I am making show very detailed pictures and instructions.

Well, I’ll take your word for it that you are CPR trained, but if I were your instructor, I suspect you would not have passed. You don’t seem to understand the difficulty or the danger of what you are suggesting.

There’s a reason CPR is the longest module in the book, and a reason why Saint John, Red Cross, and all the other organisations that teach First Aid recommend annual retraining in CPR, even for paramedics and nurses.

Sorry if I sound harsh, but CPR is just not something you can learn from scratch off the back of a cigarette pack.

This is, of course, just my crabby opinion <img src="images/graemlins/mad.gif" alt="" /> and does not reflect the attitude of Saint John Ambulance or any other organisation I work or volunteer for.
