Are oxygenated fluorocarbons used in scuba diving real?

Answer 1

oxygenated fluorocarbons are indeed real and experiments have shown that you can place a mouse in it and it will stay alive however it is not easy to get the fluid out of the lungs afterwards. As a result it is not used for humans in Scuba diving in the way it has been portrayed in things like the film; the Abyss. For one thing it would be hard to fill all of the gas pockets in the body, such as the sinuses and pressure on the body would also effect how various physical processes take place. These would probably limit the depth a diver could achieve even if oxygenated flurocarbons were used.
