I've been out of EMS for a few years now, but these have (or had at least) fallen massively out of favor.
Effectively, you could artificially keep the patient alive by using MAST pants, but they inevitably crash when they were removed. My old service had a few pairs tucked back in a closest, but none on any of the rigs. I'm quite certain they aren't in allowable by protocol in most places at this point.
A pretty wild device, nonetheless!
EDIT: Quick edit to throw in that I have heard tales from the old heads of using them to stabilize pelvic fractures, too.
I am not a dr (IANAD?) but the idea is that you inflate the pants around a patient's legs which helps both push and keep blood out of the lower limbs and closer to the hear and brain. In principle, you could do the same by tying a tourniquet around each leg but the MASTs probably cause less tissue damage and are more adjustable.
