"Fish" don't kneel ...

I think this is kinda kneeling...

What a fascinating idea!!! I found a link to some of the earlier research on this subject (probably the same research a few folks here have already referenced) from the 60's and 70's posted on another website. It looks like someone did their homework years ago and decided to shelve the idea.

I never would have guessed that the piece of kit used by the fellow on "the Abyss" was based (even loosely) on anything other than pure science fiction.

I would love to see the inventor of this new system do well and advance the technology used by divers, but he would not get very far with the testing of this contraption if it were up to me to be the guy to "test dive" it...

For those who wish to read a bit more info on the subject:

Unfortunately partial pressure is partial pressure irrespective of the interface, so the same consequences will occur Ox tox, He jitters, the bends etc ( depending on the chosen gas mix for the dive). The work of breathing liquid will be huge compared to gas ie. very uncomfortable, that is probably why he needs an extracorporeal CO2 remover, and then oxygenation can occur in apnoea. All the liquid interface will do is prevent collapse of cavities or re-expansion injuries ie. barotrauma!! Gas laws still apply. If the pO2 in the alveolus is 100, then the blood pO2 is close to 100, irrespective of the medium filling the alveolus.

hmmmm maybe ill look into designing a computer for this system ....but on a serious note im assuming there is no " gear " like this at the moment , i mean the doc doesnt have a prototype does he ? he did say he is looking for volenteers ? i want to see what that scrubber thing looks like , that will be the biggest put off , do you think the liquid willl be pink like in the movie ?

Before you get worked up too much, I thought the production of PFC's has been forbidden many years ago because they were the main reason for the hole in the Ozone layer. That hole really seems to shrink now, so maybe they were right.

Great, but wouldn't it need a replacement: ie. Nitrogen, helium, other??

Peace,

No, because it gas dissolved in liquid, not a gas media which must be displaced.

Why? Don't you catch enough fish with the conventional scuba gear?

Breathing a liquid instead of air? A tube inserted in one of my veins? :shocked2:

How do they plan on improving vision with water directly on the eye ball?
Now in order to see clearly underwater there must be an airspace between your eye and some sort of face plate.
They would need to come up with some sort of contact that could change the optic to be able to see underwater like fish or pinnipeds.

That's a neat idea. Not sure I want my eyeballs marinating in lake water, and I think saltwater would burn. I came up with an idea like this a couple years ago (the artery thing). But the idea was to have equipment oxygenate the blood also. And that means no additional Nitrogen, so no deco, ever. Only problem, is that I think it would destroy blood cells.

Oxygen toxicity alleviaion is not the theoretical advantage of liquid breathing in hyperbaric environments. Hypoxic mixtures are required with both liguid and gaseous breathing media in very hyperbaric environs to prevent oxygen toxicity.. The advantage of using a liquid breathing media is that other gasses from the breathing media are not diffused into the tissues while under pressure. Hgh partial pressure of gaseous breathing media are not required to avoid pulmonary compression (since the media is non-compressible). This would negate the need for decompression and possibly alleviate HPNS. The need for an extracorporeal co2 scrubber is that co2 off-gassing is so poor during flourocrbon ventilation, almost 10 times normal minute ventilation would be required to prevent hypercarbia (in the face of a higher viscosity breathing media). I don't see liquid ventilation ever becoming a viable recreational diving strategy.
