I understand your frustration Jace and applaud you're wanting to expand your knowledge base.

Keep in mind that you are covered by Good Samaritan laws only if you stay within the confines of what you were taught as part of an accepted training program.

Once you stray from what is taught then you're on your own legally.

With standard American Heart BLS (basic life support), oral airways are not taught (unless they've changed something in the last few weeks)

Oral airways are taught as part of ACLS (Advanced Cardiac Life Support)and even though I've been trained with them and used them in real life in the hospital, I still would be asking myself on the street "did I pay my professional liability insurance premium?"

Stick with what you are trained to do in BLS and you are already ahead of the vast majority of the population who stand around with their heads up their arses afraid to do anything.
