Yora, Something that I am sure lots of #scifi writers and gamemasters have thought about:
How bad is it when you get bullet holes in your space ship?
If you can get to safety before pressure drops to 30 kPa, you will be fine. At that point, you might have a minute or two before you pass out.
I found this equation to calculate how long it takes for pressure to drop that far:
Time(s) = [30 * volume(m³)] / hole (cm²)
For a 9mm bullet hole in a 2x2x10 meter corridor, that gives you about 5 hours.
