Will people be able to breathe freely in liquids in the future?

With gills that can breathe underwater, mutants can stay in the water for longer periods of time than normal people.

There may be ventilators or something like that in the future, but that's the progress of science and not the evolution of humans, and according to Darwin's theory of evolution, modern life came from the oceans.

This needs to be continuously studied, and it is possible to achieve it in the future.

Yes, that is to add another organ to humans, which is gills like fish.

With the continuous advancement of science and technology, this may be possible.

This should be a no-no, unless a very advanced machine is developed.

This is possible because there are many evolutionary directions for future talents.

It should be possible in the future because people's technology is constantly evolving.

It should be possible, because technology is developing at a rapid pace.

In Cameron's movie "The Abyss", there is such a plot where the male protagonist must go down to the abyss at the bottom of the sea to stop a nuclear bomb that is about to be **. In order for him to be able to breathe for a long time underwater, liquid breathing techniques were used. After an initial difficult adaptation period, the male protagonist managed to breathe in a liquid-filled hood.

This sounds like an incredible thing, and it seems to exist only in the image of the orange mind in the movie. But in fact, it is very likely that this technology will be realized in the future. The reason for this conclusion is the presence of perfluorocarbon liquids.

This liquid has a very high solubility of both oxygen and carbon dioxide. To test whether mammals can breathe in their circular signals, the scientists put mice into the liquid, and the mice quickly adapted to the liquid environment, almost exactly like they do on land. However, it was unable to breathe in the liquid for a long time, and after a few hours, the mice died.

Currently, the improved liquid is called perfluorobromide, which can carry twice as much oxygen as air, is non-toxic to the fragile alveoli of the lungs, has a low boiling point, and is able to evaporate quickly from the lungs.

However, this technology does not really enable harmless liquid respiration, and it is now commonly used in medical treatment.

It improves lung ventilation by reinflating the atelectasis and allowing less damage in the lungs or redistribution of blood flow in the atelectasis area.

In patients with respiratory failure, collapsed alveoli can be allowed to open, relieving dyspnea and relieving lung damage and inflammatory infiltrates.
