What pissed me off about this episode was that

Spoiler:

Hibito WAS supposed to be dead. When your tank runs out of supplying you with oxygen you can still last a few more minutes. Also, Hibito was not conserving oxygen at all, he was breathing too heavily to efficiently make use of what little oxygen he had left.

Also, they played out his symptoms way too quickly. By the time he went down, he should have been unconscious, not be able to get up because of the oxygen loss to the muscles in his limbs. Additionally, he was being kept at body temperature... which decreased his oxygen efficiency even further.

They really, really did favor drama over accuracy -- that to me makes the show lose a few points. I'm glad he survived, but they could have done better.
