Really? I haven't looked too much into it, but I remember reading on this forum that EMT-Bs can't even do BGL testing, at least in some states...
The differences in scope balance out in most respects. For instance, EMT-B's in some states can not do BGL monitoring while we EMR's can. EMT-B's are allowed to carry and administer Epi-Pens while we are only able to "assist" our patient in administering it (which I personally don't see much point in; if someone has an Epi-Pen, why would they call an ambulance to give it to them? If you're calling an ambulance for an allergic reaction its likely that you DON'T have an epi-pen...)
