Breathing Mediums

[jasondrake]

I read some journals on this ages ago. Doc's in america kept a dog alive for several hours on liquid breathing and it suffered no ill after effects. But the dog was unconcious throughout. Trials on adult humans were conducted - using one lung - but also when unconcious. The effort of respiring the liquid actually burned more oxygen than the lungs exchanged. So they used some sort of trembler inserted into the lung to set up currents to move the fluid around. So the breathing reflex had to be subdued with drugs. All in all not a very practical outlook. And probably cheaper to just use a robot. And to be useful, all the air spaces in the body would need to be flooded ie the middle ear and synuses to avoid compression.
