Breathe liquid ???

[Hobbs]

I was at a medical seminar about a year ago where they talked about liquid ventilation. at that time it was in the swedish medical community not something usual, I think the number was 5 people have done it, all terminally ill in some lung diseace/damage.
The liquid was rediculary expensive if I do not remember totally wrong the price /liter was something like 40 000 SKR wich translates inte something like 5000 USD and the ammount needed i think was something like 4-5 liters to vent one patient..
one of the reasons for using the liquid was that it filled up partially collapsed lungs.
and that bacteria didnt grow in it.

one problem was that the lungs produced a residue that in the end was like chewinggum, a rubery substance so they had to drain the lungs and the pumps that pumped the fluid to clean away that residue, also the liquid vapored easily so they had to add more after a while.

At this seminar there was a russian guy who had a relative who did work with this for the russian navy, and he explained that they have made tests with "test persons" and that they obviously used this type of fluid in nuclear reactors to be able to emergency stop them. so they had rooms filled with this stuff above the reactors just to dump ut right into it.
so what they have done was fill a chamber with this type of fluid and preasurised a dog down to I think it was 3 kilometers depth and then taken the dog right back up again and they took it out of the chamber dried it and it went over to one of the tables and peed at it..
and when he talked about diving obviously the navy was planning on an submarine emergency escape equipment, where you should be able to intubate yourself and to swim to the surface.

This is what was said on that seminar so thats all the reference I have on that matter..

I read somewhere that after doing this several times, lab rats had respiritory failure. BAD BAD

Look back earlier in this thread, I have a link to the company that produces this stuff -- it really is used in some cases, and quite successfully too...

I just remembered a scene from the movie "The Abyss", where they where breathing some sort of liquid to go deeper into the ocean.

Is that realizable?

Has been discussed here a couple of times: http://www.scubaboard.com/t27459.html

In short, technically feasible, but not developed enough for normal/human usage.

The technology is real, sort of. It's not to the point depicted in the movie. It is being developed in hopes that it will improve the outcome for premature babies, whose lungs are not developed enough to breathe air well.

The fluorocarbon fluid does not harm the lungs, and it will give you all the oxygen you need. The problem is, it won't accept the CO2 that you need to get rid of. That's the problem they're trying to solve, which will make it work.

The scene with the rat is a re-enactment of similar films from the lab. The rat is in there such a short time that the CO2 buildup is not an issue.

The instructor operates one of the chambers there and kept the class highly engaged with this story and similar anecdotes from the world of super-high-tech diving. Initially I thought it was bull**** but he had quite a lot of information on the navy experiments doing chamber dives with this stuff.

Unfortunately, since the course was in Phuket I have very little memory of the details.

If you are talking about Ben R, then I had a similar thing happen when he was over here. We were yarning over a beer about Dahab and other things andI asked if he knew that guy who did the 205 meter dive off the blue hole.

He replied ........errr, that was me.

I didnt know if he was joking or not, so I checked and dure enough it was him.

it was a world record a the time for a diver carrying all their gas with them for an ocean dive.

A pal of mine ( and former Diving Superintendent for Can Dive Services Ltd. - Phil Nuyton's Canadian arm of Oceaneering Intl. )
was hired as the diving co-ordinator for that film.

He said the actors were terrific to work with & eager to learn the ins n' outs of surface-supplied helmet diving, though most had never been certified in scuba! One common complaint they had though was that conventional diving helmets hid most of their faces, & they asked my buddy to modify them to accentuate their fine features. The result was the helmet used in the movie. He said they were a quick study in the use of the s.s. gear & became very proficient in its' use over the course of filming.

According to the several hours of documentary about the making of that movie, everyone was certified before shooting and none of the shots used surface supplied air. They all had SCUBA. They created a method of recharging air tanks while still under water to help save time. The exception was the deep dive suit which had a front glass visor that lifted up so that safety divers could give him air. When he is on film in the suit he is holding his breath.
Rent the special edition on DVD. There is MUCH detail in the filming of the movie. It is worth it just for the extras.

methinks Dr. Deco would know that air is a fluid

whoops, re-post.
