Mental workers must take oxygen, people who work, live, study and travel in an anoxic environment, college entrance examination students, sub-healthy people, etc. Advantages of oxygen inhalation: oxygen inhalation directly increases the oxygen content of arterial blood. Because, the human body uses hemoglobin in 70-80 square meters of alveoli and 6 billion capillaries covering alveoli to exchange oxygen and carbon dioxide. Hemoglobin contains ferrous iron, which combines with oxygen in the lungs with high oxygen partial pressure and becomes bright red, becoming oxygenated hemoglobin. It transports oxygen to various tissues through arteries and capillaries, releases oxygen to cells and becomes dark red reduced oxygenated hemoglobin, binds carbon dioxide in tissues and cells, and finally excretes carbon dioxide through biochemical exchange. Therefore, only by inhaling more oxygen and increasing the partial pressure of oxygen in alveoli can the chance of hemoglobin combining with oxygen be increased. Healthy people take oxygen:
Healthy people don't need special oxygen inhalation, and inhaling high concentration oxygen for no reason may cause oxygen poisoning.
For patients with heart and lung function defects, regular oxygen inhalation is a necessary treatment. For healthy people, oxygen inhalation can only improve the oxygen saturation in blood, but it can't play a health care role. Inhalation of high concentration oxygen for a long time may cause oxygen poisoning or other complications, but it is harmful to health.
