If you're referring to the one in the second movie, then I think that was because he was injured. After all, the one Dutch encountered didn't have trouble breathing.I had the impression that doing it on a prolonged basis might cause problems, like how we can breathe in poor air quality, but that it's probably not wise to always be doing so.Otherwise, why do their masks always cover the mouth and have an air seal?To use it in air-less environment. Ahab can have another mask to survive in suxh conditions. Another point to theory that we can use similar gas mixture was shown in Predators (not best source I know). Classic was hanging there God now how long, without his mask. Superpredators had no air seal (Classic haven`t had one either...) and himans were breathing quite ok. out there, but as I said it`s not the best source.
