Yeah, the chart miguel posted looks like what I was taught in CPR, minus the defib stuff. That's a nice study aid, thanks! (The training will teach you where on the ribcage to push so you don't break ribs, etc. -so if you think you can study the chart and skip the class, don't.)
And as for me posting the quote about Good Samaritan laws:
"Any person who, in good faith, renders emergency medical care or assistance to an injured person at the scene of an accident or other emergency without the expectation of receiving or intending to receive compensation from such injured person for such service, shall not be liable in civil damages for any act or omission, not constituting gross negligence, in the course of such care or assistance."
...and in the spirit of liability issues: DO NOT TAKE ANYTHING I'VE POSTED AS LEGAL ADVICE!
I am not a lawyer, I hate legaleese and have very little patience for reading it. I just Googled for the info and posted it without making any judgements on it's accuracy. Researching the actual law and it's applicability is up to you.
