Do you get decompression sickness when swimming

summary

Many people like diving. After diving, they will feel a kind of pressure and pain in their ears, which is decompression sickness. I'd like to explain to you whether swimming will suffer from decompression sickness.

Do you get decompression sickness when swimming

First of all, decompression sickness is a systemic disease caused by improper decompression after high-pressure operation, and the dissolved gas in the body exceeds the supersaturation limit, forming bubbles inside and outside the blood vessels and tissues. Acute decompression sickness occurs in a short time after decompression or during decompression. It mainly occurs in femur, humerus and tibia, and the slowly evolving ischemic bone or joint damage is decompressive osteonecrosis.

Then, when working underwater, every 10m of body submergence is roughly equivalent to an increase of atmospheric pressure, which is called additional pressure. The sum of additional pressure and surface atmospheric pressure is called total pressure or absolute pressure. When the body is in high pressure environment, the partial pressure of various gases in the alveoli increases and immediately balances with the partial pressure of various gases in the inhaled compressed air.

Finally, because the partial pressure of gas in the alveoli is higher than that in the blood, according to Boyle's law, the amount of gas dissolved in the blood is correspondingly increased, and then transported to various tissues through the blood circulation. Most of the oxygen and carbon dioxide are rapidly absorbed by hemoglobin and plasma components, and only a small amount is physically dissociated in body fluid. The amount of nitrogen dissolved in body fluid is directly proportional to the pressure and residence time. Due to the different solubility of nitrogen in various tissues, the distribution of nitrogen in tissues is not equal. The solubility of nitrogen in fat is about 5 times that in blood, so most nitrogen is concentrated in fat and nerve tissue. If it's just diving, it's no problem. Don't dive to a deep place. It's not decompression sickness. Be sure to put on earplugs to enter the water.

matters needing attention

Develop good health habits and establish a reasonable living system. Before work, we should have a full rest to prevent excessive fatigue; we should not drink alcohol or drink less water. People with decompression sickness should not dive in life, and should pay attention to bed rest and actively supplement nutrition.
