It pretty much does nothing until you hit 100%. The crew either dies or you surface. I have only gotten close a few times because of escorts keeping me down.
Most times it becomes a factor when you ALT exit the game or hit that damn windows sign icon on the keyboard. You can go back to the game but your O2 level will steadily keep going downs and the CO2 goes up and up until you reload a save.
