      There was no oxygen and CO2 scrubbing… Just a mask with nitrogen. The lungs exhale a mixture of oxygen and CO2, which, if not scrubbed from the chamber, will be breathed again. So in essence they asphyxiated him with his own CO2, and he died of slow CO2 poisoning as reused oxygen ran out (an extremely painful way to die). If they had done it in a hypobaric chamber and actually actively removed CO2 it would have been painless like passing out in an airplane cockpit. So yeah they somehow managed to botch a nitrogen execution with their hillbilly engineering…
