[quote=Anonymous][quote=Anonymous][quote=Anonymous]I’ve been trying to keep up with the thread but it’s moving so fast. DH and I were just talking about how the oxygen countdown is accounting for all of the passengers still being alive. If anyone has already died, that leaves more oxygen for the remaining passengers. I’m not a doctor, but my experience viewing mountain climbing movies, such as Vertical Limit, leads me to believe people could succumb to death from lack of oxygen at different times, thus extending the life of others. So the countdown seems like it’s not really on point. [/quote]

It’s just an estimate. If, after losing contact, they immediately began to conserve o2 by not talking, breathing slowly, not moving, they could extend the range. This is an article on the deepest rescue to date (at 1500 meters compared to 12-13k for titan). The two men managed to extend their o2 supply by almost 20%.

I think it’s way more likely that the 3 tourists at least immediately began freaking out and hyperventilating and the expended MORE oxygen early on than immediately shutting down and conserving. It’s 5 people in there, not 2- I don’t think they have as long as the original estimates which put them at 2:30 pm today. That was like best case scenario. [/quote]
