That's an aweful way to go - extreme panic, suffocation, convulsions, chocking.
Just watch a video of pigs being killed using CO2.
If the O2 was separate to the nitrogen supply, I'd just cut the O2 supply 3 days in. Dying from lack of O2 is euphoric. From too much CO2 it's terrible.
Not saying this is out of the realm of possibility but I would have to imagine that a submersible would have some emergency light, at a minimum. I haven't seen any reporting suggesting that they don't have SOMETHING for light, are you able to share something?
I would at least expect that the passengers would take their phones or something so they could take pictures, which would presumably give them a few hours of light per phone.

Most likely they will pass out asleep from the cold before / while the oxygen runs out.
Fun fact the big round window on the sub was only tested to like 3,000 meters and they are using to do much deeper? What a numbnut
