Even supplying fresh O2 into the room from a cylinder won't save him, unless someone finds a way to remove CO2 from the room.
- sjwright 11y agoIt's useful to remember the makeup of air: 78.1% nitrogen 20.9% oxygen 0.93% argon 0.039% carbon dioxide Carbon dioxide, in very approximate figures, is unpleasant at 0.5%, dangerous at 5%, fatal at 10%.
