Ventilation, acidosis and blood chemistry

[MDT]

unless you had a hyperbaric chamber, i'm not sure you're gonna have a "pressure diff" when you open the enclosure. I really think you're gonna still be at around 15 psi....inside and outside the enclosure....not trying to be a jerk, i promise, i just not sure you're gonna see a true physiologic change with what you describe. CO2 narcosis will occur with retention of too much CO2 and you will become very drowsy/somnolent in this state. oh well... let us know how it goes...
