I was trying to do some back of the envelope calculations on how long a person could survive in a stateroom if the life support had failed. Assuming I did my math right, a person would become unconscious in about 8hrs in 1 dton, with their capabilities being severely reduced within just a few hours (and, of course, their activity could reduce it faster). Extrapolating that out, I figured a 4dton cabin would allow for about 32hrs of consciousness. Though if you go by deckplans it should be more like 24hrs since they are only 3x2.
I found some different sets of calculations, some were using pure oxygen in the room, which isn't practical, and others were less than helpful. This one (http://kimberlymoynahan.com/2012/04/friday-fiction-facts-trapped-in-an-airtight-room/) was rather nice because it also described the effects as the CO2 built up in the room. The author also brings up a valuable point that the effects of CO2 buildup take some time to go away.
