What is the liquid substance that humans/mammals can breath and get Oxygen from it?

Question

Or is that myth....I saw this stuff on TV

Answer 1

nobody here has got it exactly right.

here's a link that will tell you everything you ever wanted to know about it (and more) http://en.wikipedia.org/wiki/Liquid_breathing

enjoy

Answer 2

there is an experimental substance like that, which was developped for diving.
A tv documentary was made showing rats sitting in it, breathing.
i have no idea wether it's really used for diving or not, but i think its not useful since breathing a liquid is not only a challenge for the mind.
i think there were difficulties getting rid of CO2 as far as i know

Answer 3

There have been successful experiments where lab rats can survive in "Heavy Oxygen Water." I think this explains it better:

[edit] Heavy-oxygen water
A common type of heavy-oxygen water H218O is available commercially for use as a non-radioactive isotopic tracer (see doubly-labeled water for discussion), and qualifies as "heavy water" insofar as having a higher density than normal water (in this case, similar density to deuterium oxide). Even more expensively, water is available in which the oxygen is 17O. However, these types of heavy-isotope water are rarely referred to as "heavy water," as they do not contain the deuterium which gives D2O its characteristically different nuclear and biological properties. Heavy-oxygen waters with normal hydrogen, for example, would not be expected to show any toxicity whatsoever

Answer 4

the water itself has oxygen for the mammals living in it. the whales would require it and of course, the fishes.. but i do not know of what you speak of.. a liquid substance? no idea..

Answer 5

jeffrey c. is correct. heavy oxygen water is based on the placenta that babies breathe when they are in the womb. when babies are first born they are taking their first breathe of air. basically the placenta is rich in oxygen & sits in the lungs so you really are not breathing as much as your lungs are soaking the oxygen from the fluids in the lungs. Keep in mind we do breathe a mixture of oxygen & nitrogen. keep in mind we breathe more nitrogen (78%) as compared to oxygen (21%) which leaves about 1% of argon & carbon dioxide.
