From Khabr, a discussion of the post about what will happen to man in the open space:

A person stayed conscious for approximately 14 seconds — approximately that amount of time is needed for oxygen-depleted blood to get from the lungs to the brain.
Yyy: Curious... And if we have a device that enriches the blood with oxygen without the use of air, can a person in this case work in a vacuum without a scavenger? Limited time, of course (let’s say a minute).
zzz: It will be N years, and the Russian, in a dispute, in some tricks will jump out of one lock of the orbital station and run into another...
