“WG”: liquid breathing under water is possible

85
The Russian Advanced Research Foundation tests liquid breathing technology for submariners on dogs, reports Rossiyskaya Gazeta with reference to the head of the Foundation Vitaly Davydov.




“In one of his laboratories, work is underway on liquid breathing. While experiments carried out on dogs. In our presence, the red dachshund was plunged down into a large flask with water. It would seem, why mock the animals, now choke the same. But no. She sat under water for 15 minutes. And the record is 30 minutes. Incredible. It turns out that the dogs' lungs were filled with oxygenated liquid, which gave her the opportunity to breathe under water. When she was pulled out, she was a little sluggish - they say, because of hypothermia (and I think someone will like to hang under the water in the bank before everyone’s eyes), but after a few minutes she became quite herself. Soon, experiments will be carried out in public, ”said Igor Chernyak, a RG correspondent.

“It was all like the fantastic plot of the famous film“ Abyss ”, where a man could descend to a great depth in a spacesuit, whose helmet was filled with liquid. She submariner and breathed. Now this is no longer a fantasy, ”he writes.

According to the correspondent, “liquid breathing technology involves filling the lungs with a special liquid, saturated with oxygen, which penetrates the blood.”

“The Advanced Research Foundation approved the implementation of a unique project, the work is led by the Institute of Occupational Medicine It is planned to create a special spacesuit that will be useful not only for submariners, but also for pilots, as well as astronauts, ”he said.

Davydov told a reporter that a special capsule was created for dogs, which is immersed in a hydraulic chamber with increased pressure. “At the moment, dogs can breathe at a depth of up to 500 meters without health consequences for more than half an hour. "All test dogs survived and feel well after a long, fluid breath," said the head of the Foundation.

Further, the newspaper writes: “Few people know that experiments on liquid breathing in humans have already been conducted in our country. Gave amazing results. Aquanaut breathed fluid at a depth of half a kilometer and more. That's just the people about their heroes never found out.

In 1980 in the USSR, they developed and began to implement a serious program to save people at depth.

Special rescue submarines were designed and even commissioned. We studied the possibility of human adaptation to depths of hundreds of meters. Moreover, the aquanauts should not be in such a heavy diving suit, but in a lightly warmed diving suit with scuba diving behind their back, being in such a depth, his movements were not constrained by anything.

Since the human body consists almost entirely of water, it is not dangerous for it to have terrible pressure at the depth itself. The body should be simply prepared for it, increasing the pressure in the pressure chamber to the desired value. The main problem is different. How to breathe at a pressure of tens of atmospheres? Clean air for the body becomes poison. It must be diluted in specially prepared gas mixtures, usually nitrogen-helium-oxygen.

Their formulation - the proportions of different gases - is the biggest secret in all countries where similar studies are underway. But at a very great depth and helium mixtures do not save. Lungs, so that they do not break, must be filled with liquid. What is a liquid, which, once in the lungs, does not lead to suffocation, but transfers oxygen through the alveoli into the body - the secret of secrets.

That is why all work with aquanauts in the USSR, and then in Russia, was conducted under the heading "top secret".

Nevertheless, there is quite reliable information about the fact that at the end of 1980-s there was a deep-sea aquastance on the Black Sea, in which test-diving submariners lived and worked. They went out to sea, dressed only in wetsuits, with scuba diving behind their backs, and worked at depths from 300 to 500 meters. A special gas mixture was fed into their lungs under pressure.

It was assumed that if the submarine is in distress and lies on the bottom, then a rescue submarine will be sent to it. Aquanaut prepared in advance for work at the appropriate depth.

The hardest thing is to be able to withstand the filling of the lungs with liquid and simply not die of fear.

And when the rescue submarine approaches the disaster site, divers in light gear will go out into the ocean, inspect the emergency boat and help evacuate the crew with the help of special deep-water vehicles.

Until the end of those works could not be brought due to the collapse of the USSR. However, those who worked at depth, still managed to award the stars of the Heroes of the Soviet Union. "

        There seemed to be problems with the salt balance of blood and the body as a whole - it was washed out of the body at an accelerated pace.

        The possibility of breathing under water was theoretically calculated somewhere half a century ago, since the tonicity of sea water is close to that of blood. And in my opinion, even similar experiments were carried out "on cats".

        They were carried out - they learned how to overcome the spasm of the respiratory tract when water got in and the test specimens completely switched to getting oxygen from the water, but I didn’t hear about the successful return of those test objects to breathing by air, but I didn’t admit the details of the experiments of those years I know - they grimaced mercilessly in Soviet times and strictly followed the performance. Something like that slipped when superimposed from subcontractors involved in the general program, nothing more.

        Where did the water from the lungs go? Dogs they are, they are rare survivability. And yet, where did they distribute the fluid from the lungs? Many times I saw people breathing with interstitial pulmonary edema, I heard at a distance how squish the fluid in their alveoli due to circulatory failure in a small circle. And here you have dogs breathe fluid for 30 minutes. Or maybe they just hold their breath? Ine for 30 minutes, and for three. That and I can.

        And not only, pumping liquid into the lungs requires energy costs 60 times higher than gas! Therefore, there is nothing surprising in the fact that the experimental animals gradually weakened, and then - due to exhaustion and accumulation of carbon dioxide in the body - breathing ceased.

      The problem is that a sufficient amount of dissolved oxygen for breathing starts from depths of 70-90 m due to the corresponding pressure, and when rising above these depths, shortage will immediately begin. It should also be taken into account, in addition to the fact that it is dark there, it is already cold at such depths even in the tropics, and since the thermal conductivity of water is 200 times higher than that of air, supercooling is ensured. In general, in ichthyander you will not get sick.

        Yes, sticks, we had doctors on our site ... So the question is, how much oxygen does a person need for half an hour (in gram moles)? You can say the air volume with normal pressure, recount.
        How much lung volume will be filled with fluid, will it need circulation, can the required mass of oxygen be dissolved in it? Yes, and lung cells, are they at least able to do a focus on the separation of oxygen from a liquid?
        Ah, biologists, crawl out .... Not all techies talk about tricky pieces of iron.
        Tfu, while you wrote, an idiotic thought, but if you store not liquid, but already prepared oxygen-enriched blood in an external capacity of 20 liters? And let into the general bloodstream?

                The baby in the womb has no vacuum in the lungs, but the lungs are not filled with fluid. At a certain period of pregnancy, the baby's lungs begin to work in a training mode, as if not for real, preparing for constant breathing in the future. The child makes the first real breath with the first cry.

          The idea is interesting, and can be discussed. At shallow depths (several meters), I think this is possible. But at great depths, if the lungs will not have the same huge pressure as in the water outside, then the lungs and chest will simply be crushed.
          There is another negative factor in the human body that is impossible to suppress - this is the process of breathing, a person does inhale and exhale reflexively, at the level of instinct. And at great depths, as written in the article, the lungs from the pressure of the respiratory mixture of gases can burst the lungs (we are talking about ruptures in the alveoli), because it is very difficult to precisely synchronize the pressure in the breathing apparatus and the pressure outside.
          Therefore, one way remains - to fill the lungs with respiratory fluid.
          In Soviet times, these experiments were once written and the fact that not a single aquanaut survived during the transition from the aquatic environment to the air. They could not remove fluid from the lungs in time.
          And your thought is not idiotic, only the lungs will also have to be filled with something.

        Ever when you inhale, a drop of water "in the wrong throat"? Remember the reaction - spasm and cough. So it is with water breathing. Plus questions with the very process of inhalation - exhalation.

            If you ensure a sufficient concentration of oxygen in the blood and the stability of its pH, then you can not breathe at all. The respiratory center located in the medulla oblongata (that is, we cannot completely regulate it - try to hold our breath forcibly - sooner or later do not stand it and breathe in) is irritated precisely by the concentration of CO2 in the blood and blood acidification. From there, the signal goes to the respiratory muscles. But maintaining a constant oxygen concentration in the blood is very difficult. In addition, there is 2 problem - with the removal of carbon dioxide, which only accumulates in the blood, but is not excreted, because there is no inhalation or exhalation. An ideal option is gas exchange through an aqueous medium that fills the lungs. However, the pH of this medium and the concentration of salt must correspond to the pH of the body; otherwise, removal of pulmonary edema and death are guaranteed. As far as I know, everything just rests on the problem of creating an environment that could carry both oxygen and carbon dioxide. The problem of filling the lungs with fluid is solvable - mild raush anesthesia and after 5 minutes you can dive.

            Drugs that "turn off" breathing have been invented a long time ago; under them and swim will not work)))
            In addition, even if you solve the problem of the immune compatibility of blood in a balloon, there will not be enough oxygen saturation of this blood for a long time, which means it will have to be oxygenated and carbon dioxide removed. Breathe in other words))) Devices for this have long existed and are used in cardiac surgery. But you won’t swim with him either))) Well, the extra volume of blood into the cylinders will have to be pumped by the same heart, and it will be hard for him, and even at a depth. As for intrauterine circulation of the fetus, this is a completely separate and extensive topic. If it is very short and primitive, then the fetus, due to broken lungs and intestines, has vascular communications, which normally close at birth. If not, these are congenital malformations that are to be treated. Well, the blood of the mother and the fetus does not mix, gas exchange occurs in the placenta.

    The practical possibility of "breathing" liquid has long been experimentally confirmed, back in the early 70s, incl. this is not news at all. There are purely technical problems, the selection of fluid and the provision of its circulation in the body. Apparently, they were solved during the experiment, apparently quite successfully, it pleases.

    But everyone forgot that not only oxygen is needed by the body? But take carbon dioxide as well. Gas exchange between fluids (blood in the alveoli and in this filling fluid) will force the fluid to circulate. And the lungs are not gills. This is how to drive the muscles designed for pumping air, a fluid with a viscosity somewhere 600 times higher? Well, a gas exchange apparatus will be required - absorb carbon dioxide, enrich it with oxygen. The volume of fluid in the lungs is not enough for a long time.

      I think that the miraculous liquid already contains such an oxygen concentration that the body needs for a certain amount of time ... And, therefore, it is not required to circulate in the lungs, that is, it is not necessary to make respiratory movements. Inhalation is completely controlled by consciousness, you can hold back respiratory movements until a decrease in oxygen concentration in the blood reaches a certain threshold and causes a reflex breath. As for carbon dioxide, the properties of this fluid should be such that it gives oxygen to the blood through the alveoli and at the same time absorbs unnecessary carbon dioxide. After use, such a liquid has a high concentration of carbon dioxide and a low concentration of oxygen, before use - vice versa.

        If the liquid contains enough oxygen in itself to provide the body for 10-15 minutes (and at best it’s 5-5,5 liters, it’s not enough to fit into the lungs of anyone), then I’m afraid this hydrogen peroxide should become a liquid, and this is death. Even if the lungs are filled with pure oxygen (gaseous), then it will not be enough for a long time, and breathing pure oxygen is very harmful. I think the fluid will have to be driven around the lungs, but the problem with the density and viscosity of the liquid incomparable with the density and viscosity of the air can be solved purely technically because there are artificial respiration devices for patients, why not make an apparatus for liquid breathing on the same principle.
        The problem with filling the lungs with fluid can also be solved. A person panics when a fluid fills the nasopharynx; he senses it with receptors. perform intubation and the fluid will not be able to affect the nasopharynx (at least until the lungs are full) and even through the tube it will be easier to drive the fluid - the throat will not interfere. That's just a sip, I'm afraid it will hurt from such mockery

        Read the pathophysiology textbook and normal physiology textbook for medical students. Your fluid with CO2 where will regenerate and be saturated with oxygen?
        And the rest of the metabolites from this liquid (for simplicity we call slags) where will they leave the liquid?

          I support. By the way, the problem of fluid can be solved by the example of perfluorane (the so-called "blue blood"). But this is before reaching a certain depth and pressure. At high pressure, it seems to me that the exchange of gases can also occur through natural membranes (alveoli). But the question arises: what then to do when the ascent and decrease in pressure - again to fill with something like perfluorane? The question is difficult, without special (or secret) knowledge anywhere ...

But it turns out that this problem can be solved this way! I am very glad. It turns out that people will be able to master the riches of the Ocean! The population density will sharply decrease, Humanity will begin to develop new territories!

      You are absolutely right. In the distant Soviet school childhood, I read about apparatuses based on membranes, which produce oxygen from water similar to gills. However, until now it has not been implemented in practice.
      The experiments discussed in the article are a dead end. Why? They do not take into account the main obstacle - how they are going to solve the sterility problem, because the infection from the upper respiratory tract will inevitably get into the alveoli with the liquid, namely, there is gas exchange. This is my answer to the enthusiasts of the discussed method for the minus in the previous comment.

      Experiments on breathing with liquid media were not carried out on the Lenkas. At the same time, in 1993, very impressive successes were achieved on this topic - a mongrel dog, a bitch, under the conditions of a complex of animal studies, without decompression plunged to a depth of 800 meters with an exposure at a maximum depth of 10 minutes. After removing fluid from her lungs, she bit the experimenters and fled. As a result of detective actions, she was found on the territory of a nearby yacht club, where she managed to get pregnant. The puppies born later showed no deviations in their development. Unfortunately, in the future, the topic was closed, they say - at the request of our American colleagues.
      Thus, all that the author of the article writes about is a check of the results achieved once. And the topic is very promising! Yes, liquid breathing equipment will be cumbersome at first. After all, inhaling and exhaling liquid, because of its large viscosity in relation to gas, will have to "voluntarily-compulsorily", otherwise the muscles of the chest will simply get tired. It is necessary to ensure its heating, to firmly maintain the required concentration of dissolved gases and to observe a lot of various necessary conditions. However, "the game is worth the candle"! After all, the development and implementation of this method will make it possible not only to make a breakthrough in the development of the depths of the Ocean! It is also a breakthrough in aviation and astronautics. After all, a special spacesuit with liquid breathing will allow the pilot to withstand colossal accelerations! And this removes the limitations of the "human factor" on the speed and maneuverability of aircraft.
      It remains only to wish the team engaged in this development of creative success and uninterrupted financing!

    terehvlad, about blue blood I’ll tell you the following. In general, real blood is, in part, that life that carries the individuality of a person and the generic (genetic) memory (of generations). Pouring artificial blood into yourself means becoming a bio-cyborg and ceasing to be a human being. I’ll say more, it’s dangerous to transfuse someone else’s blood (donor blood) into yourself, since you transfer someone else’s life into you in every sense. Here is a visual article about this. http://nepoznannoe.rolevaya.ru/viewtopic.php?id=340
    PS It is not just that for a long time there has been a rite for lovers or those who want to "brotherhood" - to make incisions on their hands and mix blood ... but this is not only biology, but also occultism ...
