I think you are making an assumption that those former EMS guys want to do EMS, which is largely untrue in very large fire departments. Those guys want to be smoke eaters.
I NEVER made that assumption. In fact, I'd say you were 100% correct that if the FD could stop responding to EMS calls tomorrow, 95% of all firefighters would support it.
But it's not about what the Firefighters want to do (or don't want to do), it's what in the best interest of the patient, and the citizens of the city.
I highly doubt the supplies are the same. Fire probably has a bvm, nrb, basic wound supplies, and maybe a functional AED; far less than a BLS ambulance.
without speaking for FDNY, on our BLS engine, we have a BVM, oxygen, an AED, a crappy electronic suction, wound supplies, albuterol, pulse ox, thermometer, stethoscope, NRB/NC/neb masks, BP cuffs, and all the bleeding control items. We also have a reeves folding stretcher for some reason. not as much as on an ambulance, but enough to do a decent assessment, and more than you are describing.
Tell me, what difference does having an EMR versus EMT assessment make when you are waiting for the ambulance?
in theory, the EMT assessment could actually determine if the patient was sick, and possibly rule out an infection, where the EMR could apply oxygen and that's about it. Remember, it's not always about what you can do, it's about what you know, and how you use that information.
Extended EMS response times in a large city is an EMS problem, not a fire problem. It should be addressed by increasing ambulances, not sending 400K 3mpg chrome chariots to belly pain calls. This is different in suburban, interface, and rural departments; but this is about real big city fire.
Extended EMS response is a city problem, not an EMS problem. Yes, more ambulances are needed, but many cities would rather pay stop the clock with an engine than actually fix the problem.
About 100,000 people have developed COVID-19 and about 3500 have died worldwide. The vast majority of people who are infected with this novel coronavirus will never develop any symptoms at all, and for those that do, most will be mild. OTOH, so far this season in the US alone, an estimated 34 MILLION people have been sickened by the flu and TWENTY THOUSAND PEOPLE have died from it.
Because the media is inspiring fear in the general public, and everyone is panicking.
Treat it as business as usual, or like a really bad case of the flu, and you will be fine. I think this whole thing will blow over in a few months
