>By that time, your real problem is simply that you've stopped breathing, which turns out to be a big deal.
With some training holding your breath for 3 minutes is doable for anyone, and the record is something like 8-9 minutes..

There's a really cool idea for a spacesuit that's basically just a fabric wet suit that's just really compressive (via electromuscles or cinched bands or w/e). That way your body gets the ability to hold onto the gas in your lungs without the risk of your lungs attempting to expand out your gut and throat.
It's an interesting idea though: what if you could train your abdomen and chest to compress a lung full of air in a vacuum? Then you just gotta keep your mouth and nose shut somehow. (It'd be really difficult - it'd take a force like trying to inflate a car tire with your mouth. Possible, but seems hard.)
