in order to really know how to do all that is invloved in pre hospital care including CPR/FBAO(unblocking airways)it really does need to be hands on training(you just have to have the experience of what it really feels like to compress someones chest during CPR to really understand the depth,among other things).i would highly advise you to just contact your local chapter of the red cross for any info.they are ALWAYS willing to help out people who are wanting to learn CPR.i used to work for them.they also offer basic first aid classes as well.i commend you for wanting to know this stuff.believe me, you honestly never know when something is going to happen.being prepared is key to a good outcome.there are many things that you could do to help save someones life while just waiting for EMS to arrive that can really make a huge diffference in the patient,and just how well they may recover.
most red cross branches also(once you have that training?)serve their communities inproviding basic first aid for special events in their areas.you could sign up for something like that once you are done and actually use those skills and keep them up.just a thought for you.it is VERY rewarding.just look them up in your phone book and make the call.they will let you know whats up.let me know how things are going. **
I think it's also possible that a local hospital in your area might teach basic First Aid classes. Either that, or your local park district, wherever you may live, or your local community college or something like that.
