Can you suck oxygen out of a room with a massive hole in it?

    That's a no.

    Also the fire suppression systems usually dump gases like nitrogen, argon, CO2 etc toreduce the O2 percentage in a room. They also don't work as well with a venting hole. A mask with a small O2 container like they use for climbing is recommended.
