Northern Maine.
EMT-B = Very limited
This would include Vitals, splinting, BLS-CPR, Driving, and fetching supplies. Of course the operation of an AED is included in the BLS-Provider course.
In Maine we utilize the Intermediate provider level of EMS
This is a nice level if you like to play but don't want that huge responsibility. In this level you may Intubate, Recognize and defibrillate VFib and Pulseless VTach, start IVs, administer a small selection of medication with doctors orders which include Nitro, ASA, Albuterol and D50. (however protocol states if the Paramedic is present, he/she must administer the Meds).
I think these advanced skills should be left to this level. All Basics who want to play more should go back to school.
