Scientists have restored the affected lungs of a person, connecting them to the swine

Science does not stand still and is constantly looking for solutions to urgent problems faced by humanity. The epidemic of coronavirus COVID-19 affecting primarily the lungs, has forced physicians to mobilize forces in a certain direction and has already yielded tangible results. Recently, American scientists from Columbia University were able to restore the damaged lungs of a person, connecting it to healthy swine.

Method of cross circulation, used to repair damaged lung donor has enormous potential in modern medicine. It's hard to even imagine how many lives can saved every year by the doctors, when will its widespread use.

Bioengineer John O'neill and the surgeon Ahmed Hasan, participated in the experiment, told the press about the significance of this discovery for treatment of diseases of the lungs:

That is, simply put, cross-circulation of pig organs was the only chance to save the lungs and the attempt was successful.

When the operation temperature of the lungs is maintained at the temperature of the human body, and through them, circulates a bloodless solution containing oxygen, nutrients, and protein. This circulation, when fluid is pumped through the body is key, perfusion part of the operation.

Scientists also said that to celebrate too early and the method must be carefully considered. It may take a lot of time, and in addition, you cannot overlook the fact that many diseases of pigs transmitted to humans. So you need to find a way to protect patients from infections that they can get in circulation.

But the main thing is already done — the technology cross-circulation is working and have a million people around the world suffering from chronic lung diseases, there is a real chance to recover.
