The way nitrogen invades the human body is inhalation. The content of nitrogen in the air is too high, which reduces the partial pressure of inhaled oxygen and causes hypoxia and suffocation. When the inhaled nitrogen concentration is not too high, the patient initially feels chest tightness, shortness of breath and weakness; Then there are fidgety, extremely excited, running around, shouting, being in a trance, and unsteady gait. This is called nitrogen poisoning, which can lead to lethargy or coma. Inhalation of high concentrations can lead to rapid coma and death due to respiratory and cardiac arrest. When divers dive deeply, the anesthetic effect of nitrogen can occur; If you switch from high pressure environment to normal pressure environment too quickly, nitrogen bubbles will form in the body, which will compress nerves and blood vessels or cause microvascular obstruction, resulting in decompression sickness.
After inhaling nitrogen, leave the scene quickly and go to a place with fresh air. Keep the respiratory tract unobstructed. If you have difficulty breathing, give oxygen. If the breathing and heartbeat stop, artificial respiration and chest compressions should be performed immediately.
Nitrogen is an inert gas, generally speaking, it will not cause any harm to human body, but a large amount of nitrogen may reduce the oxygen content, but it will lead to local hypoxia, so this big bag should have little to do with it, and it is estimated that it is caused by other reasons. If you have other discomfort, it is recommended to go to the hospital.
The harm of inhaling nitrogen is that you can drink water and warm water, which has no effect. Don't eat cold food during menstruation, pay attention to the warmth of the abdomen, especially the navel.
The harm of nitrogen is that liquid nitrogen can easily lead to frostbite. If you can get oxygen, try to get it. If you can't get oxygen, reduce your activities. A short rest usually relieves.
The chemical formula of nitrogen is N2, which is colorless and tasteless. The chemical properties of nitrogen are very inactive, and it can react with hydrogen to produce ammonia under the conditions of high temperature, high pressure and catalyst. In the case of discharge, it can combine with oxygen to produce nitric oxide; Even active metals such as calcium, magnesium, strontium and barium can react with them only by heating.
