If it is not a special situation it is best not to sleep with oxygen concentrator oxygen. Only people who are hypoxic need to inhale oxygen. If you are doing oxygen therapy at home, you also have to look at the blood oxygen partial pressure and blood oxygen saturation two indicators. People whose partial pressure is below 60 mmHg or whose oxygen saturation is below 90% need additional oxygen. If there is no oxygen deficiency, there is no need for oxygen at all.
If oxygen is administered blindly, it can have side effects instead. If healthy people short-term high-flow oxygen intake, but will cause oxygen poisoning, manifested as a burning sensation behind the sternum, dry cough, nausea and vomiting, irritability, dyspnea and other symptoms. High oxygen concentration leads to lung tissue damage, oxygen masks or oxygen catheters are not sterilized can also lead to a higher risk of respiratory infectious diseases.
If you're going to take oxygen, be sure to get a partial pressure and oxygen saturation test beforehand.
Oxygen concentrators have a role to play in hypoxic populations, such as chronic obstructive pulmonary disease, asthma, bronchodilatation, gas poisoning and other diseases, when the patient appears hypoxemia need to use oxygen therapy to alleviate the symptoms. Home oxygen therapy does change the course of COPD, though it must meet the indications and be done under a doctor's supervision.
Expanded information:
According to the current Chinese People's **** and National Pharmacopoeia, the concentration of medical Oxygen concentration of ≥ 99.5%. However, the reporter found that many oxygen products on the product parameters and description of the introduction of the labeled "oxygen concentration range ≥ 90%", the specific concentration of how much, and not clearly marked, therefore, the sales staff so-called "medical standards" publicity, there are misleading consumer The suspicion is that the salesman is misleading consumers.
"Theoretically, a home oxygen concentrator can make a patient's oxygen saturation reach more than 90%." Bai Chunxue emphasized, but the premise is that consumers will operate. Currently on the market with oxygen concentration monitoring function of the oxygen concentrator is not much, the people at home is difficult to grasp the concentration of oxygen. If the oxygen given less than enough, give too much, not only waste, but also damage to the body.
Shen Huahao frankly, he has been practicing medicine for 30 years, did not recommend the use of home oxygen concentrator, some patients with chronic obstructive pulmonary disease, can receive oxygen therapy at home, but that are medical oxygen cylinders, under the guidance of a doctor to use.
He Quanying also does not recommend that people buy their own and use them at will. He pointed out that, after all, home oxygen therapy has indications, in addition to the need to master the use of the method, but also need to do the assessment of the efficacy of oxygen after inhalation and according to the efficacy of the adjustment of the concentration of oxygen inhalation, these issues need to be resolved under the guidance of a doctor.
"The current home oxygen concentrator market management is relatively chaotic." An oxygen concentrator salesman revealed that the state for the low-temperature air separation method of oxygen, according to the management of drugs, but for home oxygen concentrator this molecular sieve oxygen equipment is not included in the management of drug management system management, but is included in the management of the second class of medical devices, the standard is looser, so there are a lot of manufacturers to produce oxygen concentrator.
"In fact, the identity of medical oxygen has been highly controversial in recent years." An industry source told reporters that, according to the Pharmacopoeia, oxygen belongs to the drug, it should be included in the management of drugs, the strict implementation of the standards and regulations of the drug, but now the molecular sieve system of home oxygen products and is included in the second class of medical devices, obviously contradict each other, and for the molecular sieve oxygen specification documents have not yet been issued.
The reporter visited some medical equipment stores found that some of the oxygen generator has a medical device approval number, there is a class of oxygen generator even the approval number of the medical device is not. The State Food and Drug Administration 12331 telephone staff told reporters that if there is no such approval number, it is not a medical device.
For this point, the sales staff explained that there is no medical device approval number belongs to the "health care equipment". In this regard, the industry pointed out that the country does not have "health care equipment" this category, this type of oxygen concentrator can only be attributed to the management of small household appliances, claiming that the effect is difficult to guarantee.
