I need supplemental oxygen at less than 1 fathom under water, if I stay there long enough...

    I highly recommend using compressed air over oxygen. Nitrox 100 (pure oxygen) becomes toxic below 5 meters...

    1.6 bars partial pressure Oxygen is considered unsafe / hazardous.

    Nitrogen also becomes toxic, requiring you to substitute it with helium (or hydrogen).
