Nitrogen that creates bubbles in the blood
Nitrogen also causes circulation problems and causes inflammation. If you think about the principles of divers, the answer is simple. When you scuba dive with compressed air, you breathe in extra oxygen and nitrogen. The body uses oxygen, but nitrogen dissolves in the blood and remains in the blood during the dive. During diving, nitrogen will dissolve and accumulate in the body in proportion to the time it stays underwater, right? When you swim to the surface of the water after a deep dive, the surrounding water pressure gradually decreases.
At this time, the decrease in water pressure is too fast and there is not enough time to remove nitrogen from the blood, so it vaporizes and creates bubbles in tissues or blood. Just like when you suddenly open the lid of a cider bottle, bubbles form in your body. These bubbles block fine capillaries and impede blood flow, causing various symptoms called diving sickness.
Nitrogen must be carried in the blood along with oxygen, travel throughout the body through blood vessels, and be expelled through the lungs. It is a physical phenomenon that gas dissolved in the blood becomes bubbles in order to pass through the acini of the lungs. If you stop breathing at this moment, the foamy blood cannot come out and returns to the heart. What will happen if this happens? If you turn back without being able to go your own way, it can cause circulation problems and inflammation in the joints.
