Recently, the State Food and Drug Administration has warned against the abuse of oxygen concentrators. How to choose the right oxygen product? Many problems such as how to reasonably inhale oxygen need to be viewed rationally, normal people do not need oxygen, those who do have symptoms of oxygen deficiency as a means of treatment, can be used correctly under the guidance of a doctor, do not follow blindly, oxygen as a life-saver, but also against the reckless exaggeration of the dangers of oxygen, fear of rejection, home oxygen is really easy to poisoning? Oxygen deprivation may be a disease or some manifestations of a disease. When oxygen deprivation is present, there may be headache and dizziness, distraction, inattention, memory loss, sleep disorder (increase or decrease), slow reaction, panic and shortness of breath, chest tightness, general weakness, etc. In serious cases, there are symptoms such as mental depression and coma. The oxygen saturation and partial pressure of oxygen may not fall when there are symptoms of hypoxia, but once there is a drop in oxygen saturation, it indicates that hypoxia has reached a more obvious degree. Second, those causes can cause hypoxia Hypoxia has five categories, including hypoxia, circulatory hypoxia, blood hypoxia, toxic hypoxia and relative hypoxia caused by increased oxygen consumption, life in cardiovascular disease caused by circulatory hypoxia caused by the reduction of circulating blood volume, highland areas due to thin air, air pressure drop caused by hypoxia, brain workers are mostly relative hypoxia caused by increased oxygen consumption Inhalation of high concentration of carbon monoxide or other harmful gases is toxic hypoxia, and when the disease develops to a certain degree, it is mixed hypoxia. Third, what are the products available for home oxygen intake The representative oxygen products in the market are Oxygen Lidl, oxygen bag, oxygen cylinder, oxygen machine, soft oxygen chamber and so on. The oxygen bag is safe and reliable, but the oxygen storage capacity is too small, suitable for short time use, about 30 minutes per bag; the oxygen bottle has a large oxygen storage capacity but has certain safety risks, at present, the hospital does not have the qualification of oxygen filling, only the oxygen factory can complete, how to fill oxygen is the biggest problem in the use of oxygen bottles, most of the oxygen machines are molecular sieve oxygen production, convenient to use But the oxygen concentration is not up to the medical oxygen standard, molecular sieve oxygen production will gradually decline with the extension of the use of years, and there is a lack of corresponding supervision and inspection mechanism, whether the use of a year or more after the national standard? It is to be further regulated in the market; the soft oxygen chamber has only entered the market in recent years, and the person enters the chamber and pressurizes with the oxygen generator to improve the purpose of oxygen deficiency through high pressure, the operation is more complicated, and the market price is tens of thousands of dollars. No matter what kind of oxygen absorbing products you choose, different oxygen absorbing methods directly determine the oxygen content and oxygen reserve in the body, which will eventually produce different oxygen absorbing effects. 1.Nasal catheter or open mask oxygen inhalation is a traditional oxygen inhalation method commonly used at present, because a large amount of air is also inhaled during oxygen inhalation, the partial pressure of oxygen inhaled is about 250mmHg, the amount of oxygen inhaled is less (the partial pressure of oxygen in air is 159mmHg), in addition, the oxygen still flows out continuously during exhalation, so it causes half of the oxygen to be wasted. 2.Oxygen inhalation by normal pressure closed mask Only when inhaling, oxygen will flow out, and when exhaling, it will be closed automatically, which will not cause the waste of oxygen, and the partial pressure of oxygen inhalation is 760mmHg. flexible cabin does not need to wear oxygen inhalation tube or mask, it is inhalation of oxygen-rich air under higher pressure, which is different from oxygen inhalation by ordinary oxygen machine. The occurrence of oxygen poisoning is related to two variable factors: oxygen concentration and continuous oxygen intake time, usually nasal catheter oxygen intake for 10-15 days, closed mask oxygen intake for 6-8 hours before the possibility of overdose poisoning. As long as there are symptoms of oxygen deficiency, it will not cause obvious damage to human body if used correctly under the guidance of a doctor. Dependence includes mental dependence and physical dependence: mental dependence refers to the patient’s perverted craving for the addictive drug to obtain the perverted pleasure after taking the drug. Somatic dependence refers to the pathophysiological changes in the central nervous system after repeated use of a drug, so that the patient needs the drug to persist in the body in order to avoid the specific withdrawal symptoms caused by the withdrawal of the drug. Oxygen inhalation obviously does not have the above conditions, oxygen inhalation treats or relieves the symptoms of hypoxia, and does not bring any special pleasure, so oxygen inhalation will not produce dependence. 3.Choose the suitable oxygen inhalation method The different methods of oxygen inhalation directly determine the amount and efficacy of oxygen inhalation. Traditional nasal catheter oxygen inhalation is usually suitable for respiratory system diseases due to the small amount of oxygen inhalation, other cardiovascular and cerebrovascular diseases cannot reach the effective oxygen content of the body and the expected oxygen inhalation effect; closed mask has a large amount of oxygen inhalation, which is faster and more significant than drugs from the perspective of improving hypoxia, and is suitable for all hypoxic diseases without carbon dioxide storage. diseases, i.e., most hypoxic diseases other than respiratory diseases are suitable for this method of oxygenation; the flexible chamber can be used as long as the body can withstand the change in pressure. The purpose of oxygenation is very clear, that is, to improve hypoxia or the damage caused by hypoxia, the way to improve hypoxia mainly includes the application of vasodilators, improve oxygen utilization, artificial hibernation or cold compresses (to reduce oxygen consumption), blood transfusion (to increase oxygen carrying capacity) aerobic exercise and oxygen absorption. As long as it is used correctly under the guidance of doctors and professionals, it can achieve a certain blood oxygen content and has a therapeutic effect on hypoxic diseases, especially for those who suffer from cardiovascular diseases, oxygen absorption and vasodilator drugs have the same purpose, the latter is to improve hypoxia by increasing blood flow, as long as oxygen absorption The latter is to improve oxygen deficiency by increasing blood flow, as long as the oxygen absorption method is properly chosen, it is beneficial to the disease, for each individual what kind of method to take can be considered according to the condition and environmental conditions.
