An average room will sustain a person for a decent while. At rest, an adult consumes approximately 550 liters of oxygen in 24 hours. Room air is roughly 20% o2. An average room might be 14x10x8 feet... 32,000 liters. One adult at rest for 48 hours reduces the o2 concentration in this room from 20% to 16.5%. The Internet says one might lose consciousness around 7% o2. Take that for what it's worth.
That said, do not assume air circulates magically. I used to have a "Perfect Victim" style under-bed confinement system, which was a light-controlled space, and as you might expect it was considerably smaller than a room... it also had redundant air circulation fans in light baffled blinds.

Re: Internet Controlled Prison Cell
Don't forget that as O2 concentration drops, CO2 concentration rises. That's the killer.
Anything above 5% and you're in trouble. Even at 3% you have potentially harmful effects.

Re: Internet Controlled Prison Cell
Good point, Jenny, and closer to an issue in this scenario. An average adult at rest cycles 15 breaths per minute of 0.5L volume, which is:
- 7.5L / minute
- 450L / hour
- 10,800L / day
- 21,600L / 48 hours
Exhaled air from a full breath contains 4% CO2, so in our scenario thus far the room level of CO2 rises from background (0.03%) to 2.7%. Your link suggests that this level is not noticeable at rest but may generate shortness of breath under exertion... which could itself accelerate both breathing and introduction of CO2. You're certainly right that CO2 presence will become an issue before O2 absence. In a 10x10' room with 8' ceiling, 48 hours brings CO2 to nearly 4%, so this is sensitive to room size.
In any case, including planning for a shorter period, I would suggest that it's simple to force some ventilation without introducing light, and even a small air exchange solves the issue entirely.
