Yup, it’s part of why the idea of rescuing them was never going to happen either. There’s only something like 3 subs in the world that can dive to that depth and they weren’t close enough nor built for rescue missions. Even if they were alive they only had 3 days worth of oxygen. Honestly they’re lucky that the “sub” just imploded rather than dealing with the slow loss of oxygen.
I’m not sure about that, hypoxia could be a fun time. CO2 poisoning would just be sleepy… So not as fun I guess. Waiting to die would definitely be lame though.
Try again. High CO2 is highly uncomfortable. You cannot catch your breath, headaches, confusion, body has to deal with blood trying to go more acidic… CO2 poisoning is anything but a nice nap.
Exactly. Your lungs don’t burn when you hold your breath because O2 is low, they burn because CO2 is high. Any other gas to displace the O2 is undetectable (aside from irritants and smells). It’s why huffing helium doesn’t burn but can make you light headed faster than you realize. That’s why CO poisoning is so dangerous. CO2 poisoning is torture. And yet CO2 pits are still legal for kill pits…
