If you were exposed to the vacuum of space under the least harsh conditions, do your lungs collapse or can they maintain their shape? Maybe something in between fully collapsed and their natural shape?

Second, if you were intubated before hand, could enough oxygen be pushed over the surfaces of your lungs to keep you alive? I would imagine that this would be a very low pressure flow and would be completely open to the vacuum. I suspect that if your lungs partially collapse, perhaps yes, but you would do damage to the lung tissue as that O2 forced it's way out.
