    I didn't know exactly where this fits in so I chose here.

    A little information

    "One idea that is being researched to prevent the need for saturation diving and decompression at great depths is liquid breathing, which was also shown in "The Abyss." Instead of breathing gas, the diver breaths a non-compressible, liquid perfluorocarbon compound that contains oxygen.". http://science.howstuffworks.com/science-vs-myth/everyday-myths/question640.htm

    So is liquid breathing possible?
    It seems so...
    But what's the time table it would be used?
    Would it be usable to say just the Navy?
    Would you have tried this? It seems kinda neat.
    Have you seen Abyss, its a old movie I re saw it today, that is what got me thinking about liquid breathing.
    So has anyone got a clue who is all doing this type of research? Has it been tried on humans? Or is this a "doomed project"
    What's your thoughts an ideas on this, anyone?

    I've seen that movie at least 3 times. Don't know much about that process, but breathing liquid is way not natural. I couldn't do it, even if I knew it would work.

    Currently there are no liquid breathing chemicals for humans, I've herd it work on mice but the total volume that there lungs move is a lot less than a human and thats the problem. You have to move a large tidal volume which has to contain a high concentration of O2 desolated AND it has to be able to give that O2 up rapidly across a lung field and further more it has to be able to take up CO2 and other gasses out of the lungs rapidly

    Surely it would make breathing quite a lot harder.

    Liquid breathing is what I call DROWNING!

    I would not be the first to give it a try but I would go second if it was successful.

    You need a mechanical means to move the liquid into and out of the lungs; normal breathing labor would tire one out too quickly.
    I suspect that you'd also need a way to exchange the gases in the liquid very quickly to get rid of the CO2; maybe some kind of buffer to react with it.

    All do-able, but imagine you're in some deep sea trench, and the little motor that pumps your lungs gives out. It's not very safe.

    Maybe "artificial gills" are the way to go for CO2 exchange:

    This was in 2010, anyone know of any more recent developments?

    That is absurdly dangerous. No, no, a thousand times no.

    I'm kind of shocked that somebody is seriously proposing this.

    The person who "invented" that should not have been given a patent either, as that solution is actually pretty obvious, just too dangerous. Unless he developed a way to make it non-dangerous?

    Better just to motorize lung filling to get a proper respiration rate to exchange the CO2. Or potentially alternate breathing solutions (oxygen providing and CO2 removing).
    Another solution might be to isolate the lungs, and have the Oxygen-in lung on one side, and the CO2 out lung on the other side. You'd need a nasty tube down your throat- though better than having blood sucked out of a major artery into a machine: at that point you don't even need lungs (you can just aerate the blood directly).

    I thought it was called "water boarding"?

    With a little DNA modification we might be able to grow up with gills and that could be very good for getting some very high paying jobs. On the other hand being called a freak might mess with your mind a bit.

    With gills think about the land mass we could occupy under the sea...

    If getting gills is safe an effective, an I still can breath regular air. I would sign up for that an be like aqua man. An I would be like kevin in water world.
    Only issue I see with gills is we would most likely be fresh water breathable. There may be water that could potentially kill us. As there are some "creatures" that can not breath out of there "water table" an being "human" even with gills I would think some pressures would not be safe. Our bones are not solid they may break under some pressures.

    As long as we are playing with DNA I'm sure we can arrange both types of water. We would also need some way to equalize pressure to keep us safe at depth. But what about our skin? After a day or two in water it doesn't do to well.

    By the way whatever happened to aquaman anyway?

    I think maybe a shark got him.. I don't know.
    Maybe someone here knows though. I would like a answer. Although there usually are a lot of different "tales" that are told based on the "years". Some stories variations come out every year some longer than that. Shit look at batman as an example. It came out I think in the 30's. The criminals stay the same but the story matter changes.
    But back to the op.
    If we have to alter our DNA. We will never get approval!

    There's always someplace in the world where approval won't be needed.

    But were you may go to get approval. You may not have the top notch equipment needed. Or the brightest minds.
