What's Cryogenics And The Way Does Freezing Our Bodies Work?

A British schoollady has been cryogenically frozen after she died from cancer, within the hopes that she may be "woken up" and cured in the future.

The 14-yr-old asked a High Court choose to rule that her body might be preserved after her mother and father disagreed about her wishes.

She wrote to the courtroom: "I feel being cryo-preserved gives me a chance to be cured and woken up, even in hundreds of years’ time. I don’t wish to be buried beneathground.

"I want to live and live longer and I believe that sooner or later they could find a treatment for my cancer and wake me up."

Mr Justice Peter Jackson ruled that the lady’s mother, who supported her want to be frozen, ought to have the only real right to decide what happened to her daughter’s body.

The case was the first of its kind and has been hailed as a landmark ruling for cryogenics. But how does the process work?

What is cryogenics?

Cryogenic freezing is the process of preserving a dead body with liquid nitrogen.

Advocates consider that scientists will someday work out easy methods to warm the our bodies up and bring them back to life, by which time doctors could be able to treatment cancer and other illnesses which are untreatable today.

At present, cryogenic freezing can solely happen as soon as someone has been declared legally dead.

How does cryogenic freezing work?

Freezing needs to start as quickly as attainable after the affected person dies to stop harm to the brain.

First, the body is cooled in an ice bathtub to gradually reduce its temperature. In some cases CPR will also be administered to prevent brain cells from dying.

Doctors will then drain the body of all blood and change it with an anti-freeze fluid designed to stop dangerous ice crystals forming.

The body is then packed in ice and transferred to a facility in the US or Russia.

On arrival it's put into an arctic sleeping bag and cooled by nitrogen gasoline to -110C over several hours.

In the course of the next two weeks, the body is slowly frozen until it is at a temperature of -196C.

It's then suspended in liquid nitrogen and switchred right into a "affected person care bay", the place it should stay indefinitely until science advances.

Cryogenics facilities also supply the choice of neurocryopreservation – where the head is removed and frozen with out the body.

Scientists theorise that in the future a new body may very well be cloned or regenerated for the head to be attached to.

Does cryogenic freezing work? Has it been completed?

Those who join cry-preservation achieve this hoping that science will in the future convey them back to life.

At the moment, docs would not have the information required to reanimate a frozen corpse.

The Cryonics Institute says that dogs and monkeys have been revived after having their blood changed with anti-freeze and cooled to below 0C, but to not full cryonic temperatures.

Nematode worms have been preserved on the full -196C and revived, and in 2005 a rabbit kidney was frozen at -135C and efficiently transplanted to an animal.

It is not uncommon for human embryos to be frozen for use in IVF procedures.

How much does cryogenic freezing cost?

The schoollady’s household paid around £37,000 for her body to be preserved, mentioned Mr Justice Jackson.

The minimum charge for the Cryonics ci institute in the US is $28,000 (£22,5000) plus a one-off membership price of $1,250.

The place can it be done?

There are only three organisations on the earth that supply cryogenic freezing: the Cryonics Institute in Michigan, US – the place the schoolgirl is now preserved, Alcor in Arizona, US and KrioRus in Russia.
