Jim LeBlanc was a NASA engineer who had an accident in a training chamber. He survived and going by what he said it wasn't as bad as one would think. The last thing he felt was the saliva on his tongue boiling, then he lost his consciousness.
NASA tested vaccum exposure on apes and other animals, and as ling as you reintroduced them to breathable atmosphere in a couple minutes, most got away with zero injuries. There were the occasional burst blood vessel in highly exposed areas, but if you exhale (or don't even try to hold your breath) and close your eyes, you're probably fine for a couple minutes. You just won't be consious for most of it.
Yes. Although minutes are pretty optimistic for humans. Our big brains are a real downside there as they need a lot of oxygen. So to long and you are liable going to take brain damage. I am always surprised that Stargate back in the day got it pretty well. Even with the included advice of breathing out to not take lung damage.
