in NY state EMT-B's can do BLS work, splinting, assist with nitro and epi pens, give O2, use a defibrillator, board and collar...all that stuff...
we have a level called EMT-CC (critical care) who can administer meds, start IV's, EKG's and intubate as well as BLS stuff
and then at the top is Paramedic..they do everything...
