We respond to 80-90% medical calls. Normally there is 3 on the truck and 2 on the ambulance.
Two people cannot run a “bad call” effectively. Many times, the patient is wedged between the commode and the wall in a 4’ square bathroom or the wall and the bed. First you have to drag them out to somewhere to work them. This poses a problem when they weigh 300lbs.
My son says a truck is sent out with every ambulance to manage the fatties.
