My CPR cert lapsed and i just want to bang it out real quick to move on to taking the exam but i don't know which organizations are officially recognized by the registry
Like the others, I would suggest that the NREMT just wants a CPR course that is geared toward a professional responder/healthcare provider. The AHA and ARC both have such a course, as do others. HCP courses from nearly any provider will generally follow the AHA or ARC HCP course standards so as far as NREMT is concerned, if your state recognizes it as an HCP CPR course, so will they.
