I confused le la.. Haha. Yong Hua's description damn difficult to uds. Haha. But I dun think got more oxygen ba, oxygen tanks contain near 100% oxygen, you can't possibly fill the entire cabin with oxygen right, that'll be damn ex... And the CO2 the ppl produce will lower the percentage of oxygen too fast anw...
