I saw an advertisement a few days ago advocating the 'benefits of oxygen', and even suggested that the family should absorb oxygen when they are free, not only 'for the benefit of whole-body organs', but also for 'prevention of cardiovascular and cerebrovascular diseases'. Role. This is nonsense. Unless we are in an oxygen-deficient environment (such as high altitude areas, special operating environments), or suffer from respiratory diseases, anemia, and other diseases that lead to hypoxia in tissues and organs, Not conducive to health, it may also be harmful.
Not only healthy people, but also patients with cardio-cerebral vascular disease, should not routinely absorb oxygen in the absence of oxygen deficiency. In this regard, a number of studies have been conducted abroad, and as a result, it was found that as long as oxygen saturation ≥ 94% ( An indicator of whether or not there is a lack of oxygen in the blood), conventional inhalation of oxygen in patients with myocardial infarction or cerebral infarction would not be beneficial, or even harmful. For example, in a trial published in 2014, the blood oxygen saturation of ≥ 90% of acute Patients with myocardial infarction were randomly divided into two groups: one group received routine oxygen inhalation and one group received no oxygen inhalation. The average follow-up period was 6 months. The results of the study showed that the creatine kinase level and troponin levels in patients receiving conventional oxygen inhalation (this is two The less favorable indicators were all higher than those in the non-oxygen group, myocardial injury, recurrent MI, increased risk of severe arrhythmia, and increased myocardial infarct size. Another study confirmed that there was no hypoxemia. In patients with acute myocardial infarction, conventional oxygen inhalation does not reduce mortality; in patients with acute heart failure without hypoxemia, routine oxygen inhalation may lead to vasoconstriction and decreased cardiac output, aggravating the condition; chronic heart failure patients also should not routinely absorb oxygen.
Oxygen is still the case for the 'efficacy' of patients with cardio-cerebral vascular diseases, not to mention healthy people. At present, many physically healthy people take oxygen as a 'healthy' measure. There are even many 'oxygen bars' on the streets. There are some preparations for the entrance exam. The students of the college entrance examination will absorb oxygen before the exam. Despite the current lack of such research, but inferred from the above research results, I am afraid that there will be no benefit in doing so. What is lacking, no shortage, do not make up, This is true for all kinds of nutrients or oxygen. Personally believe that if there is no special situation, do not have to take oxygen.
