Was thinking about that wonderful scene in 2001 when Dave Bowman blasts himself into an airlock with no helmet on.

Then I started thinking... if you go from say normal atmospheric pressure, to vacuum, to normal atmospheric pressure again, even in a short space of time like 10 seconds, wouldn't you get the bends?

Bends requires that first you live under so much pressure that you get nitrogen dissolved into you blood. Only then will a drop in pressure allow the nitrogen to evaporate into gas bubbles in your tissues.

As an astronaut you apparently won't get bent in 10 seconds or so of
vacuum exposure. There is a lot of material on this on the intartubes.
Good places to start might be:

Nitrogen is still dissolved in your tissues even at 1 bar.

He may not get the bends after such a short exposure, but I bet that ten seconds would hurt. A lot.

It's amusing to me that what most people find unbelievable about this scene is that Bowman's head doesn't explode when he enters vacuum. Outland set a bad example, and so many movies have followed suit that it's become conventional wisdom that the human body pops like a balloon in space.

In the Real World (TM) he would probably be OK as long as he did not hold his breath. Proof of this I leave to the reader's Googling skills. :D

The bends effects are very varied and yes the Bowman would have experienced the bends...It would have most likely be a muscle or skin hit...rapid expansion

But it would have gone away quickly once pressure was restored.

What he did was just barely do-able, which is plenty for the story.

As they say, don't try this at home...
