Technology allows people to breathe underwater

Russian scientists have developed technologies that help submarine sailors crash and emerge safely.

Humans and other airborne organisms often drown when there is too much water in the lungs, but Russian scientists have demonstrated that a dog can survive underwater, using liquid breathing technology in experiments. To save lives of submarine crew, Sputnik News reported.

Breathing is a form of respiration in which organisms breathe through oxygen-rich liquids instead of the usual air.

For decades, scientists have sought new ways to save submarine crews in distress and help pilots and astronauts withstand harsh environments on long flights.

In scientific experiments, a dachshund dog is immersed in a container filled with oxygen saturated liquid. Only two minutes later, the dog was able to adapt to the new environment.

"The fluid enters the lungs and the animal begins to breathe with liquid," the researcher explained in an experiment in Moscow on Dec. 19.

The liquid method developed by the Institute for Advanced Studies in Moscow can be used to rescue submersible submarine crews. A rapid rise from a depth of 100 meters is impossible because the release of nitrogen bubbles blocks blood vessels in the spinal cord and brain, which can be deadly.

To avoid this danger, the submarine will be equipped with a special device that pumps oxygen-rich oxygen-filled liquids into the lungs. As a result, the lungs will not be compressed by external pressure, which will increase the atmosphere by 10 meters. The pressure of the body is balanced with external pressure, allowing the user to emerge safely without experiencing a prolonged suppression.

The method could also be used to protect fighters and astronauts from the enormous weight they suffered during high altitude take-off and maneuvers. With fluid-breathing technology, researchers can create a uniform to distribute weight on the pilot's body.
