There's no way to cool down a patient, core temperature included, using a gas
as heat exchanger in required time frame, period. Adding a sleeping bag makes
the problem worse (~2 day descent for inner core, you're mush -- look up
those CI threads on Cryonet).

What is wrong with a thumper and a portable ice bath?

Water is a liquid, you will observe.

When you're drowning in ice cold water, you still have circulation. Your periphery shuts down
first, and your core temperature can come down as low as ~25 C before you're
out cold due to fibrillation.

This works best with small children, which can be reanimated up to 45 min
(I don't claim this is the longest time). Small children = good
volume/surface ratio, low body fat index, and good shape in general, as well
as excellent regeneration (there might be additional protection mechanisms at play).

Good for cooling beer, sure. Good to cool patients, no.
