Good for you bro. Ive been doin EMS for only 5 years, and its great.
My advice?
Listen to the salty medics. They will teach you more then any book will. This job is 99% OTJ. School can give you the info, but Ive seen alot of book-smart people, that cant function for s%$# in the field. Know where everything is on your truck, there is no excuse for not knowing. Nothing pisses me off more then having students on ride alongs, that sit in a chair studying the backs of their eyelids,or buryin their nose in a book. When your riding, RIDE! Learn the trucks, and the equipment.
Start memorizing your skill sheets, and practicing them right off the bat, dont wait for it to be covered in class. Be able to perform complete assessments in no less then 5 minutes. Dont get tunnel vision, focus on your pt as a whole, dont zero in on one prob, and miss a life threat.
YOU HAVE TO CRAP YOUR PANTS AND DIVE IN. DONT STAND ON THE SIDELINES.
you have to. Thats the only way to really learn, and impress the preceptors. I hate the know it alls, who talk it up, then when it comes down to it, just stand there.
Get a BP cuff and steth, and take everyones who comes in your house. I did it, and it helps alot. Take BPs in the car when your riding with people(not when your driving

) A BP sounds alot differant at 70mph then in a living room.
Treat your pt, not the equipment. You will know soon what I mean by that.
Utilize your resources efficiantly. IE cops, fire, and helicopters. They are there for that. Always make sure evryone knows who is in charge. PTs, bystanders, and resources. It pays to be a dick sometimes.
Any help needed......Shoot me an Email. I think I have some assesments lying around you should memorize. Mine are excellant, not the book crap. My instructor made em, and if you memorize them, you will have no trouble passing boards, or forgeting a step. I will mail you copies. Shoot me your addy.
