General Administration of food and Drug Administration issued a reminder: it is mostly boasting that the health care of oxygen inhalation is not reliable

In recent years, "oxygen absorption" has become a fashionable word Many people prepare their own oxygen generator at home to absorb oxygen Therefore, the oxygen generator has become a gift giving choice for many people However, recently, the State Food and Drug Administration issued consumption tips, pointing out that the oxygen generator should be purchased and used under the guidance of doctors At present, there is no evidence to prove that oxygen inhalation has health care effect on normal people On the contrary, improper oxygen inhalation may cause harm to human body Recently, when investigating the market of oxygen generator, we found that many manufacturers are exaggerating the effect of oxygen absorption In these manufacturers' advertisements, oxygen inhalation seems to be able to help solve most of the daily uncomfortable symptoms, and the oxygen generator has become a "health care artifact" On February 12, the reporter searched Taobao and found more than 6000 oxygen making machine products, with prices ranging from tens of yuan to tens of thousands of yuan The reporter saw on the website of an oxygen making machine, which is known as the No.1 sales volume of the whole network, that the product named "oxygen Wizard" costs 1488 yuan, saying that "taking oxygen every day can not only improve immunity, but also improve work efficiency and quality of life", and its applicable population is also "one net to kill": in addition to the special patients, there are office workers and students, pregnant women and the elderly, etc The other 950 yuan "light of life" oxygen machine is known as "fighting against air pollution, making clean oxygen for Chinese people", and it is said that white-collar workers and students can "eliminate fatigue, refresh their mind, improve sleep", pregnant women can "promote the growth of fetus", the elderly can "improve immunity, prolong life", not only "health care" ”And "beauty" In addition to the hot sale of household oxygen generators, manufacturers have also launched car oxygen generators Although the selling price of a "aize portable oxygen bar car oxygen generator" is only 33 yuan, it is packaged as a "health care artifact" in its product introduction: students can use it "to make their mind clear and thinking quick"; white-collar workers often use it "to relieve nervous tension and maintain vigorous energy"; when they feel tired for a long time, they can use it immediately "to drive with energy and ease" Drive " Normal people do not need to take oxygen many healthy people choose to take oxygen, think that there can be disease treatment, disease prevention Who really needs oxygen? Cui Rong, deputy chief physician of respiratory department of the First Affiliated Hospital of Tsinghua University, told reporters that the oxygen generator has certain effects on people with hypoxia, such as chronic obstructive pulmonary disease, asthma, bronchiectasis, gas poisoning and other diseases For patients with serious cardiopulmonary disease, family oxygen therapy can play a certain role, but it must also conform to the indications and be carried out under the guidance of doctors She stressed that only people who lack oxygen need to breathe oxygen If they are doing oxygen therapy at home, they have to look at two indicators: blood oxygen partial pressure and blood oxygen saturation People with partial blood oxygen pressure below 60 mmHg or blood oxygen saturation below 90% need additional oxygen Cui Rong pointed out that normal people do not need oxygen therapy at all Healthy people can supplement the increased oxygen consumption through their own compensatory mechanism, and the oxygen in the air can fully meet the needs of the body The magic effect of oxygen inhalation is mostly boasting Can oxygen inhalation with oxygen generator really bring health care, beauty and anti haze effects? As for the theory of aerobic beauty, Li Guangrui, director of Dermatology Department of Wangjing hospital, pointed out that there is no evidence that aerobic beauty can be achieved, and aerobic beauty is purely conceptual hype, because the skin surface of human body can not directly absorb oxygen, even through pressure oxygen injection, hand massage and other ways, oxygen can not enter the skin Many oxygen generators claim that pregnant women's oxygen inhalation "can promote the growth and development of their babies" Experts point out that at present, there is no evidence that pregnant women's oxygen inhalation can promote the growth and development of their babies, and normal pregnant women do not need to take extra oxygen at all, unless they are pregnant women with hypoxemia Many oxygen making machine products claim that oxygen inhalation can alleviate the harm of PM2.5 Cui Rong pointed out that the concentration of pollutants in the air and the concentration of oxygen are two concepts The oxygen making machine can not solve the pollutants that have been inhaled into the body, and it has no significance to alleviate PM2.5 Moreover, blind oxygen inhalation may also bring side effects "Oxygen therapy" has its indications, specific methods, dosage and treatment course If a healthy person inhales oxygen with high flow rate in a short period of time, it will cause oxygen poisoning, which is manifested as burning sensation, dry cough, nausea and vomiting, restlessness, dyspnea and other symptoms behind the sternum She suggested that if you want to take oxygen, you must do a test of partial pressure and saturation of blood oxygen in advance Experts in the registration certificate No for the purchase of medical devices remind that consumers should purchase and use medical devices under the guidance of doctors, and should not blindly purchase and use medical devices When purchasing, you should select a qualified unit to purchase, carefully check the product registration number and relevant information of the manufacturer, and pay attention to ask for invoices and shopping vouchers, check the contents and keep them properly When purchasing relevant products, it is necessary to recognize the "medical device manufacturer license" The name of the manufacturer and the registration number of the product shall be indicated on the outer package of the qualified products Consumers can also log in the website of the State Food and drug administration to verify the product information In case of sales exaggeration and propaganda, report to the local food and Drug Administration in time.
