Is it possible cryogenically freezing a living person?

Cryogenic freezing – something out of science fiction. Anyway, it might seem that a few decades ago. Now many are seriously interested in the question of whether you will discover at one moment to freeze, and then “order” revival in the future? And since this topic is interesting and relevant, should try to find the answer.

Terminology

You should Start with the consideration of such things as cryonics. It came from the Greek word κρύος, which means “frost” or “cold”. This technology, thanks to which the preservation of animals and people in a state of deep cooling possible. Do this in the hope that in the future they will be able to spice up and even cure.

To date, However, cryogenic freezing of people and large animals may not be reversible. This means that once the “konstruirovat” them in the future to revive will not work. The same applies to frozen brain and head. Why? Because cryogenic freezing of humans occurs only after it has been legally recorded death. Otherwise it would be considered murder.

But then why do it? The fact that some scientists believe that brain death is theoretically final. And they hope that once the technology reached a level of development that will allow you to revive these frozen people.

Many people actively support this idea. In 2016, had composed an open letter sent in support of cryonics, and it was signed by 69 scientists from around the world. But the hypothesis concerning a possible after the death of recovery of the information contained in the brain, I believe the unprovable.

Proof of probability

Of Course, no one would argue that cryogenic freezing of humans is possible without tangible evidence.

In 1966, for example, failed to prove that the brain restores electrical activity after freezing to -20 °C. In 1974, conducted an experiment in which gray matter was partially restored its activity after 7 years of storage under appropriate conditions.

In 1984, it has been proven that large bodies are not subject to structural damage during freezing. And in 1986, the researchers found that large mammals can be brought back to life in case if they three hours will stay in a state of clinical death at a temperature of -3 °C.

In 2002, conducted an experiment, in which proved that the brain retains memory even if it is cooled to -10 °C. In 2004, doctors performed a successful transplant of kidneys after freezing at -45 °C and subsequent warming.

The Following experiment, conducted in 2006, proved that the complex neural connections retain their ability even with vitrification (the transition of a liquid to a glassy state).

In 2015, the world learned that the animal is subjected to freezing and revival, has not lost its memory. In the same year, conducted an experiment on cryopreservation and recovery of whole brain of a mammal. The researchers said it was perfect.

Believe in our country?

Cryogenic freezing of people in Russia is widely perceived as a fraud. This was repeatedly stated by the Chairman of the Commission of the RAS, working against falsification of the research and pseudoscience. Freezing think a commercial undertaking, with no scientific justification, and also the fantasy that speculates on people's hopes and dreams of eternal life.

But at the same time there are supporters. They say that now, of course, there is no doubt about it, but after 30-50 years, can open up such opportunities through which really manage to recover the man from the frozen state. And by the way, about 15% of Russians would not oppose the cryopreservation themselves or their families – it is found out through the survey conducted «Levada Center».

“Kriorus”

12 years ago in Russia formed a company called KrioRus. Their work – cryogenic freezing. That is, the storage of the bodies of their dead “patients” in liquid nitrogen. Moreover, the company offers frozen as whole body or just the head.

By the Way, «Kriorus” is the only Russian organization conducting the freezing Pets. To date, their storage, their future will have three birds (including the goldfinch and the blue tit), 2 cats, 6 cats, 7 dogs and 1 chinchilla. Must be very fond of his pet, to do such a thing. Because cryogenic freezing of an ordinary cat is worth $ 12,000.

The same price and on the preservation of the human brain. Freezing the whole body costs 36,000 dollars. Still available the so-called VIP-freeze in a cryogenic chamber. The question price-150 000 dollars. Of the benefits – cryo-bracelet thanks to which a human activity can be tracked. In the event of death of the place leaves a rapid response team. There are still some “advantages” (if it is appropriate to say in this context), but they can be found individually.

Preparation

Cryogenic freezing of the body is so complex that logical. Therefore extremely important to develop, implying the production of special solutions. If you already have a finished concentrate, then it will make 32 liters, necessary for cryopreservation of the head.

When the solution is ready, it is passed through vacuum sterilization, which is carried out by using special filters. As long as the cryogenic frost in Russia is not very popular, all liquid substances freeze until you need them use. When you receive the “patient”, the solution is thawed, and the procedure begins.

Next step

The First thing you do with a human body after death – was cooled down to 0 °C. It is so important that if “client” turned to the experts in advance, it is recommended to prepare the ice packs. Because immediately after the heart stops, begins the destruction of his body. All the processes previously responsible for the maintenance of life, cease to exist. And stop the destruction of the body is capable of either ice or chiller chemical origin.

After that, the specialists have access to the circulatory system. It is usually done by either the pathologist or the surgeon. Or specialist company which provides a service, such as cryogenic freezing.

Photos that are now available in the public domain, show that the procedure is very similar to conventional therapeutic surgery. In its course the experts will get access to the jugular vein and carotid artery. This second stage begins and ends with the last –.

Connect system for perfusion

After all the previously described stages in the arteries and veins of the body are inserted into a special tube. With their help, blood is excreted from the body. And the body is filled with a solution. To control the process, using such a device as a Refractometer. With it is possible to identify the percentage concentration of the solution in the tank (which in this case acts as the body).

60 % - it is this degree of saturation are installed by specialists. Once achieved this figure, the procedure done. Blood completely replaced with solutions. We cannot allow even the smallest part of it remains in the body. Because in this case, the processes of change will accelerate.

Here, however, is the answer to the question about how the cryogenic freeze. Then the body is placed in the vault. The operation itself lasts about 4 hours, the patient are 6 professionals, including 2 surgeons and 4 assistants.

Procedure alive

Many keenly interested in the question: "is it Possible to cryogenically freeze a living person, and not deceased?" Well, one can say with certainty: at the moment it is not practiced. In the beginning of the article mentioned that this procedure is equivalent to murder. But there is still additional information.

Many may think, say, Yes, the recovery seems possible, if freezing were subjected to a living person. However, this procedure is carried out with a dead body! Doesn't that seem strange?

Specialists Have the answer. They argue that the fundamental difference between the living and dead in this context, no. At the initial stage for sure. Because any man within 15 minutes after death is considered, in principle, alive – with the help of modern technology it can be brought back to life. And the statement that the brain is starting to happen, irreversible changes – is a myth. In any case, experts RIOCENTRO lead rebuttal in the form of complex scientific theories. But still, until that freezing a living person is impossible.

The young “patient”

In 2015 were produced probably the most unusual of cryogenic freezing of a human. Photo “patient” below. This is a 2-year-old girl from Thailand named Maturin, Navaratan. She is the youngest person who ever experienced this specific “conservation”. // создаём пока пустой массив, где будут жить наше оглавление const links = []; // находим все подзаголовки и добавляем им id, который состоит из слова h2- и порядкового номера этого заголовка [...document.querySelectorAll('h2')].forEach((el, i) => { // присваиваем id каждому элементу, добавляя к нему порядковый номер этого элемента el.id = `h2-${i}`; // отправляем в наш изначально пустой массив новый элемент с уже готовым HTML-кодом для ссылки links.push(`
