CRYOCONSERVATION is the preservation of the human body after death in a state of deep cooling in order to revive and heal it in the future, when the achievements of medicine and other technologies will allow it
Science knows cases when people who died as a result of deep cooling were resurrected, while maintaining a sound mind, sober memory and physical strength.
For example, what such "defrosting" was experienced by a resident of Japan Masaru Saito. In the hot summer of 1967, the driver of a refrigerated truck decided to rest and cool off in the refrigerator compartment of a truck transporting blocks of dry ice. The refrigerator door suddenly slammed shut, and the chauffeur was trapped. When they took him out of the refrigeration chamber, he was in a completely frozen state and showed no signs of life. But in the nearest hospital he received urgent medical attention, and he came to life.
Among those who died from hypothermia, there are record holders. The residents of Canada were in the state of “registered death” for the longest time: Edward Ted Milligan was dead about two hours, and Jean Jobbone - about four. Returning home on a blizzard January morning after a night away, she suddenly lost consciousness. At seven in the morning, Jean was found by a bystander, but due to an unfavorable coincidence of circumstances, she was brought to the hospital only an hour and a half later. Her heart had already stopped beating, there was no breath. For that. seven doctors and ten nurses fought to bring her back to life. They succeeded.
But the most striking incident occurred in Mongolia. Here in the winter of 1987 a boy, frozen in the steppe, lay for 12 hours in the snow in 34-degree frost. When the boy was found, he had no breath or pulse. After the provision of emergency medical care, a hint of a pulse appeared - two beats per minute. It took many hours of work by the resuscitators until they managed to regain their breathing and hear the boy's faint moan. A day later, he moved his finger, then his hand. Fully consciousness returned to him only after two days, and a week later the boy was discharged home with a laconic conclusion: "There are no pathological changes."
"A MAN CAN BE RESURRECTED!"

If after death from the cold a person sometimes comes to life, then this process can be made manageable. Scientists came to this conclusion based on the analysis of "natural wonders" and began to develop the necessary methods.
The pioneer was the American physics professor Robert Ettinger. who published the book "Perspective of Immortality" in 1964, in which he outlined the main ideas of cryonics. It began with the tempting promise that most living people have a good chance of resuming their physical life after death, since bodies frozen and stored at ultra-low temperatures are subject to only minor changes, and in the future new technologies will allow the revitalization and rejuvenation of frozen organisms.
Based on this. Ettinger founded the first cryogenic firm in Washington DC, the Life Extension Society. Then came the New York Cryonics Society, the CryoCare Corporation and the California Cryonics Society. The latter, in 1967, carried out the first scientific freeze in history. This first patient was American psychology professor James Bedford. Upon learning that he was dying of lung cancer, he himself agreed. to be frozen in liquid nitrogen and brought back to life when medicine defeats this deadly disease.
Doctor of Medicine Mikhail Soloviev, one of the main supporters of cryonics, proposed for our country a model of "Societies of the Immortals" in the form of farms where subsistence farming is conducted, with equipment for storing bodies and installations for the production of liquid nitrogen. The safety of frozen patients will depend only on the labor of the inhabitants of the farm. The more people who want to live forever, the less everyone will have to pay for their "resurrection". With this strategy, cryonics can become very cheap - on the order of one to two thousand dollars per "body" - and people practically stop getting sick and die
HOW THE "CRYOCONSERVES" DO
From a technical point of view, the freezing process is not too difficult. But there is one caveat here. It is allowed to start it only with the prior written consent of the patient and only after doctors ascertain his clinical (cardiac and respiratory arrest) and biological (cessation of the bioelectrical activity of the brain) death. In this case, cryopreservation can only be subjected to a living, even if agonizing, but still a living person. Nobody will undertake to carry out this procedure with the deceased.
Trying to resurrect it after freezing is like reviving a mammoth corpse found in permafrost.
After this, the agonizing "dead man" is connected to the artificial circulation system. It oxygenates still living tissues. The blood is then gradually replaced with cryoprotectants. and the body itself is cooled for several days to the temperature of liquid nitrogen - minus 196 degrees Celsius.
At the same time, glycerin and a 2% solution of a special substance are added to the cryosolution to freeze the brain to a glass-like state.
In a year, the body, immersed in sound sleep and frozen, will age no more than one second of its life under normal conditions
All ingredients accompanying "artificial" death, except for liquid nitrogen and glycerin, are kept in the strictest confidence.
Then the body, solid as ice, is wrapped in plastic, put in a sleeping bag and placed on an aluminum pallet in a cryostat - a metal thermos 3 meters high and 1.5 meters in diameter, filled with liquid nitrogen, which is periodically added as it gradually evaporates.
A typical cryo chamber holds four people and is kept upside down for emergencies because nitrogen stays at the bottom longer.
