We are told all doors are airtight on a starship, which seem to imply the air circulation/supply system is independant for every room. The suggestion in the CRB is that life support systems are related to the staterooms. So I would assume that as long as air is able to come from these areas to the occupied areas of the ship then the crew would get the standard 'life support' duration of air. Food & water would be seperate considerations.
I would add only the caution of
as normally engineered to your assumptions. In other words, when everything is sunny things work exactly as you say. In a very serious situation (I would hope!) systems can be rejiggered for lifeboat-style survival. You know, even a Rolls Royce limo has tires to burn for a signal and radiator water to drink... probably not what was originally intended for the occupants!
At any rate, I'd assume a ship would have the wiring and pumps and redundant engineering to accommodate just about any plausible, amazingly creative "Flight of the Phoenix" scramble for survival. And I'd give the PCs at least that much chance for survival... wouldn't kill them per the CRB :wink:
