Thinking back to the days when Nie Weiping reigned over the chess world, sucking oxygen, repeatedly saving the day and building a successful career. I believe that many people still remember the exciting picture. Oxygen inhalation has become Nie’s “unique weapon”. A recent report revealed that Zhao Benshan also often inhaled oxygen to refresh himself when he was physically exhausted. Oxygen health care is gaining attention and more and more people are trying to improve and maintain their health by taking oxygen. Modern research shows that the existence of sub-health states is related to the lack of oxygen in tissues and organs. The common symptoms of dizziness, drowsiness, and easy fatigue in subhealthy people can often be effectively relieved or even eliminated with oxygen therapy. The anti-aging effect of oxygen is also more confirmed. As people age, repeated damage to vascular endothelial cells, accumulation of metabolic products, and increase in blood viscosity, tissue cells farther away from blood vessels will suffer from insufficient oxygen metabolism, hypoxia, ischemia, and accelerated apoptosis. Giving them adequate oxygen supply regularly and correcting the state of tissue cell hypoxia and ischemia in stages can slow down and reduce the speed and quantity of cell death and achieve the purpose of prolonging life. The key to whether a person needs extra oxygen supplementation is to determine whether there is hypoxia. If there is a deficiency, it is supplemented, and if it is supplemented, it is well. In fact, people living in the city, shuttling through the jungle of steel and concrete, breathing the somewhat turbid air, bearing the pressure of work and life, especially those white-collar workers who spend their days with computers, and students who are urged by the sound of midterm and entrance exams all day long, often have different degrees of hypoxia. Oxygen intake is the most direct and effective way to improve oxygen deficiency in the human body. For this group of people, oxygen health care has an important role that is difficult to replace. There are three types of oxygen therapy and oxygen health care: general oxygen inhalation, atmospheric saturation oxygen inhalation and hyperbaric oxygen supplementation. Normal oxygen is the most commonly used method of oxygen delivery, usually using nasal plugs, nasal cannula or mask oxygen, the actual oxygen concentration of inhaled oxygen can reach up to 45% to 50%. Saturated oxygen is a special method of oxygen inhalation that is nearly twice as concentrated as regular oxygen inhalation. It circumvents the “half-open” phenomenon of losing some oxygen through the nose during regular oxygen inhalation, and can increase the dissolved oxygen in the blood of oxygen users by six times, which greatly increases the oxygen supply to the body. Hyperbaric oxygen therapy can increase the dissolved oxygen content in human plasma more than 14 times, and has some other special therapeutic effects, the most significant effect of improving the body’s hypoxia. In addition to the indications and contraindications, there are also some restrictive requirements in the process of oxygen supplementation, such as the patient must wear cotton clothing, cannot bring cell phones, MP3s, iPads and other electronic products, must concentrate on the cabin treatment, the cabin activity space and mode are restricted, and cannot enter and exit at will. On the whole, saturated oxygen is a kind of oxygen supplementation method which is especially suitable for the health care needs of the sub-healthy people. For most people, the specific oxygen intake plan is to take oxygen once a day for no more than one hour, stopping for 5 minutes in the middle of each inhalation, and taking oxygen 10-20 times in a row. A special reminder is that additional oxygen supplementation is similar to clinical medication, how do you use it? How much to use? How much and for how long? It should be done under the guidance of professionals. In addition to the amount and time of oxygen supplementation, we should also pay attention to the ventilation of the room to avoid fire hazards caused by high oxygen concentration in the room.
