I have been on two "chamber rides". The USA civilian profile is (or was) a gradual decompression that stops at 25,000 feet with all test subjects wearing masks. Each subject in turn removes his/her mask and has time to experience his/her own syptoms and reduction in cognition. No one is allowed to experience loss of consciousness but sometimes a subject is very reluctant to put the mask back on.
I suspect this 25,000 ft exposure would be very different from slow or rapid depressurization at FL340. (My chamber rides were for high altitude glider flying and I have no experience as PIC of pressurized aircraft.)
