Hyperbaric oxygen therapy as a unique medical treatment, in recent years, popular in some candidates before the college entrance exams, especially in some of China’s major cities such as Beijing, etc. Some candidates through hyperbaric oxygen therapy to obtain promising results, but some are not, whether hyperbaric oxygen can improve academic performance, people have different views on this, there are many different opinions, here we would like to briefly talk to the majority of candidates and parents about Here we would like to briefly discuss some information about hyperbaric oxygen therapy. People usually live in an atmospheric pressure environment, hyperbaric oxygen therapy is a medical treatment method to get rid of diseases and fitness by inhaling pure oxygen in a medical environment higher than an atmospheric pressure. Why is it that among the many losers, there is no shortage of top students who usually learn well, and among the lucky ones there are also candidates who usually learn in general, where is the key to their failure and achievement? In fact, the most critical in the state of the exam! For students who are sprinting for the college entrance examination and using a lot of brain, the most crucial thing is to keep the brain and body in good condition. Because, no matter how good the usual learning, if not played out are useless, once the appearance of love to doze off, inattention, reaction than flat slow, memory loss and other symptoms. It means that the child is in a state of brain fatigue. The brain is the most active and energy-consuming organ of the human body, the brain consumes 40% of the oxygen in the body, the direct cause of the brain fatigue of students in the exam is the brain oxygen deficiency, to solve the brain oxygen deficiency, the most critical is to replenish the oxygen consumption, to want the child to sprint for the college entrance examination can hold up, appropriate oxygen, especially hyperbaric oxygen is beneficial, because of this, in some cities before the popular examination students for hyperbaric oxygen therapy is not surprising. It is not surprising that hyperbaric oxygen therapy is popular in some cities. The principle of hyperbaric oxygen to improve performance is to solve brain hypoxia. Our normal breathing, including the oxygen inhaled through various oxygen absorbing equipment at atmospheric pressure is carried through a combination of things called hemoglobin, the amount of oxygen combined with hemoglobin is a certain limit, when the partial pressure of arterial blood oxygen reaches 26.6kpa (-200mmHg), the oxygen saturation of hemoglobin will reach 100%, it can no longer combine oxygen. According to Henry’s law, the gas solubility law is that at a certain temperature, the gas solubility is proportional to the pressure, so the physical oxygen solubility in the plasma increases with the increase of oxygen partial pressure in the hyperbaric chamber. High pressure can increase blood oxygen concentration by 7-21 times, which is much higher than oxygen intake under normal conditions. Hyperbaric oxygen increases the partial pressure of oxygen through the specific environment of high pressure, which increases the diffusion distance of oxygen and enhances the transmission ability, so that the brain tissues get sufficient oxygen supply, and the amount of oxygen stored in the brain tissues and other tissues is increased, so that the brain’s ability to tolerate hypoxia is enhanced. Tissue metabolism is strong, cell survival time is prolonged, so that the brain’s reaction ability is improved, thinking is sharp, and the total effect is not generally replaced by the use of drugs. Of course, to improve the performance, must be the usual study has a certain foundation of people, if the usual foundation is not well, and want to through a certain therapy speed writing for excellent results, it is very difficult. If the candidate has the foundation now and feel brain fatigue, want to improve the performance, in order to let the candidate read “easy” a little, for the candidate to the best state to carry out the high school entrance examination sprint, if convenient, may wish to apply the hyperbaric oxygen.
