However, this aversion includes the common mistake of holding a deep breath, which in reality would cause serious lung damage as the depressurized air expands beyond lung capacity.

Averted in the Cowboy Bebop episode ' Heavy Metal Queen' when Spike transfers between ships using only earplugs for protection and a couple gunshots to adjust his trajectory.

then being Kenpachi, simply flies out of the pocket and slashes at Gremmy. Kenpachi screams in silent agony as his lungs start to burst and his eyes almost pop out of his head.

In Bleach, Gremmy Thoumeaux uses his Imagination-Based Superpower to form a pocket of outer space around Kenpachi Zaraki.To get an idea of how low that is: a soda can is pressurized at about 2 to 3 atmospheres above ambient pressure. Most space missions never come close to this, though, as they generally use pressures of 1 atm or less. If you're interested, google the 'Byford Dolphin' incident - but beware of Nausea Fuel. These chambers are only slightly less dangerous than the alternative of having the divers spend hours underwater as they ascend very slowly. These pressure gradients are usually only found in decompression chambers meant to allow deep-sea divers to return to the surface without contracting the bends. Or, to be more precise, at least 7 or 8 atm (atmospheres), with 1 atm being normal atmospheric pressure. That said, an explosive decompression can happen in real life if you get a really high-pressure gradient - from far above-normal pressure down to atmospheric pressure, say. As one of the great classics of Hollywood Science, the belief in explosive decompression is so widespread that audiences are more outraged when it doesn't happen (see The Coconut Effect and Reality Is Unrealistic). Good luck getting all of this across to most audiences, though.

It is far less likely if the decompression occurs slower than about half a second, which is quite common in sci-fi. Pulmonary barotrauma (lung rupture) is possible, but not guaranteed. Incidentally, holding your breath would be worse than useless the difference in pressure would cause a serious and fatal embolism even from the smallest amount of air in the lungs resulting in death even if someone manages to rescue you.
