The fire extinguisher is not just for show
so your EMT partner..... ventilated them with a BVM? maybe dropped an OPA, and suctioned as needed? I'm guessing your EMT partner did what any competent provider would have done, and the student handed them the equipment that they asked for?I'd just like to shamelessly plug Texas EMS here, again. My EMT-B partner and a student single-handedly managed a difficult airway with BLS means and pre/re-oxygenated her to the point where the (difficult) intubation was safe and routine. You won't get to do that in SoCal.
Not to shamelessly plug NC, but I did that my second call in NC as a first responding EMT on a QRV.......
