Don't forget that most HEMS isn't really made or trained for doing SAR. Landing at off airport sites and flying limited IFR is about as dicey as it gets. One person might be able to get to a victim and stabilize them but moving, packaging a patient to get into a helicopter takes more than one guy who is likley exhausted from donning the suit, getting there and doffing his gear. Just send the helicopter in the first place. Since they'd likley need a helicopter anyway, just shorthaul an EMT in and land as near as possible. Much faster. Although.......it would probably make for some awesome GoPro video. Also, I wonder, can these little turbo jet engines set things on fire? They aren't the hydrogen peroxide jet packs like the Bell jet belts or yore. I've only seen video of them flying off fire resistant surfaces and over water. It was news to people when they realized that Ospreys fighting fires with buckets could actually burn things and melt Bambi buckets if folks weren't careful of the exhaust.
