One question. Is an EMT-1 rather like an EMT-basic? that is, in Colorado EMT-basics DON'T learn how to really read an EKG. they don't know the drugs, or the doses, or the effects. If you get an EMT-intermediate or paramedic (both require EMT-B first), then ACLS is mandatory and you get all that information.
Having been an ACLS instructor for several years, many people struggle with drugs and dosages. If you don't know your drugs, study hard. Pharmacology is the number one fail module in paramedic school. Get your dosages down right. Learn how to read your EKG strips cold. Don't worry about axis deviation and advanced EKG stuff like that... the basics should do you fine. Also, learn how to run a cor. Everyone has to take a turn at leading a cor scenario... this means you have to tell your team what to do.
On a lighter note, I thought ACLS was an absolute cake-walk. However, as an ACLS instructor I have failed doctors, many who didn't know the difference between a junctional rhythm and a-fib. Most doctors/med students going through ACLS the first time have NO CLUE what drug doses are supposed to be (one rather memorable experience... this poor med student had no idea about drugs or doses... and since he gave 100mg of lidocaine, he then gave 100 mg of epi!! Good thing it was just class and not a real patient). Many nurses absolutely sweat ACLS because they dont' know their rhythms. Although they are absolutely stellar on drugs.
Give it a try. You've got nothing but a hundred bucks or so to lose. 🙂
