Title: What is liquid breathing and how does it work?
Post by: Ricardo on 05/11/2008 16:31:36

Ricardo asked the Naked Scientists:

Years ago (10-12) someone told me that there is some sort of liquid/water that was developed by scientist for Military Special Operation Groups, such as Navy Seals, SAS and some others. Now if it's true, then what its composed of?

What do you think?

I COULD BE WRONG BUT I believe what they used was a highly aerated & low viscosity fluoro carbon. Low viscosity as it takes a lot to move fluids it in and out of your lungs and to high a viscosity would put strain on your heart causing it to fail.

I have heard they have used it medically but if it could be perfected would be a major step forward for deep sea diving as a liquid isn't compressible.

Or just to rinse your lungs out when you've got a cold!

Fluorocarbons. There goes the greenhouse effect again.
