I'm trying to determine how long I can stay submerged before having to surface and vent the sub.
yes, CO2 can kill your crew.
i. myself, have never experienced CO2 above 28-29 on the meter at the base of the HUD, so i cannot say at what point crew performance is affected or at what point crew begin to die.

i have, on more than one occasion, ordered a rapid surface and re-dive in order to dispel the CO2 and restore the O2 supply. this was done at night, of course.
