Liquid breath

We think that we can breathe only by breathing in air. But it is not so. We can breath in water too.It is exactly the world of SF. But it is real.When We breaht,our lungs exhaust carbon dioxide and takes oxygen.This is called exchange oxygen. When density of oxygen in water is very high our lungs can exchange oxygen.This breath method is more effective than artificial respiration.Actually this technology is used in prematurely born baby who cannot do artificial respiration that sends lungs air.I celebrate that this technology saves many life.
