Original Note:
as the photo clearly show, the sub is carrying cylinders clearly marked "compressed AIR", only 22%oxygen, no rebreathing system. Expired nitrogen, CO2 and unused oxygen bubbles away. Spacesuits carried pure Oxygen in a rebreathing closed circuit for 7 hours, not 22. https://en.wikipedia.org/wiki/Apollo/Skylab_spacesuit#Apollo_15-17,_Skylab_and_ASTP_Spacesuits
