Trope-a-Day: Almost Out of Oxygen

Almost Out Of Oxygen: Still happens occasionally, despite every spacecraft’s emergency kit carrying an ample supply of oxygen candles and lithium hydroxide (because CO2 poisoning is what’ll actually get you; or, well, if the thermal management system isn’t running because of the same problem that’s taken out the life support, you’ll cook) – or the appropriate equivalents for non-oxygen breathers – against exactly this contingency.

Of course, given the realities of space distances that we covered back in Escape Pod, if you should find yourself playing this straight, it almost certainly means you’re dead, or at least your current set of bodies are.  So it goes.
