More interesting is exactly how the ship "creates its own gravity" - something which is glossed over in many sci-fi stories...

Actually, the problem you face is that even if you tried keeping your mouth shut and holding your nose, there are other openings through which the gases inside your lungs could escape. Eustachian tubes. for example. The effect of suddenly being propelled out into space (ambient pressure 10-8 bar) would be rather like an explosive decompression in an airliner, only even more severe because of the pressure differential. The gases inside your lungs would exit through any available orifice, and at speed.Gawdzilla Sama wrote:First off, the pressure has to drop suddenly INSIDE your body. Keep your mouth shut and hold your nose and this will happen much slower. The boiling is in proportion to the gas pressure, and that rate I don't know. Anybody? 98.6 F liquid boils at what air pressure?
It would take somewhat longer for dissolved gases in body fluids to begin making their exit, though I can think of a couple of unpleasant routes by which this would be achieved, Any body tissue comprised of semi-permeable membranes on a significant scale would facilitate such escape. The kidneys being a prime example, and moreover, being organs with a connection to the outside, albeit somewhat indirect. Another issue that would be manifest fairly quickly is gas embolisms in the bloodstream, as dissolved gases began making their escape via the same mechanism you see whenever an agitated Coke bottle is opened. The water content of the bloodstream itself would take a little longer to start transitioning to the gas phase. According to Kaye & Laby's Tables of Physical & Chemical Constants, the vapour pressure of water at 38°C is around 6.6 KPa (1 bar = 101 KPa, so the vapour pressure of water at 38°C is approximately 0.06 bar). Boiling (wholesale transition to the gas phase) takes place when the vapour pressure is greater than or equal to the surrounding atmospheric pressure, so at 10-8 bar, the surroundings are well and truly below the pressure at which the water content of the bloodstream would transition easily to the gas phase, though it would take time for that pressure differential to make its presence felt in the bloodstream itself. Gas embolisms would occur first, and transition of the water content to the gas phase would follow shortly afterwards. Though this transition would also be slowed by the elastic pressure of the blood vessels.
Apparently, animal experiments have determined that 90 seconds is the critical period of elapsed time. If an explosively decompressed animal is brought back to normal atmospheric pressure before 90 seconds has elapsed, resuscitation and recovery is possible. After 90 seconds, however, full-body exposures are invariably fatal. A paper covering this is listed on PubMed here, but finding more details is a little tricky at the moment.
However, not all organisms expire after 90 seconds. Tardigrades have been demonstrated to survive exposure to Low Earth Orbit conditions for up to 10 days. The relevant paper covering this finding being:
Tardigrades Survive Exposure To Space In Low Earth Orbit by K. Ingemar Jönsson, Elke Rabbow, Ralph O. Schill, Mats Harms-Ringdahl & Petra Rettberg, Current Biology, 18(17): R729-R731 (September 2008) [Full paper readable online here, PDF download from here]
