Injectable oxygen keeps people alive without breathing
<i>...who would be able to breathe underwater for 30 minutes at a time without coming above for air.</i><p>This seems like a loose interpretation of "breathe".  But leads to a question I had -- assuming the injection described in the article works properly, what would the result of inhaling water be?  I can't imagine it's very comfortable, but assuming the person's oxygen is handled by this injection, would the body adjust?
