Done the two man litters...yes, litters.
"Stretchers" refer to a particular type of litter which has longerons running parallel to the pt's body (well, unles they're all accordioned-up) and two or more lateral stiffeners which would "STRETCH" it out so it didn't collapse from the sides. Oddly, the government nomenclature for this item was/is "D-Ring Litter"..the first ambulance litter, fit into military vehicles.
Correct, archaic and disused terminology for these folding units designed to go into an ambulance as "ambulance litters". FernoWash et al call them "ambulance stretchers". Oh, well.
Can't speak about the new ones, but the older ones are potentially dangerous in the hands of unschooled people like my coworkers...dangerous to the pt, dangerous to the person handling it. Those guys with the Hearse were lucky, lifting those two-man mothers especially uphill into a modular was murder for most.
