In patients with acute heart failure without hypoxemia, routine oxygen inhalation may cause vasoconstriction, decrease cardiac output and aggravate the condition; Patients with chronic heart failure should not routinely take oxygen.
Extended information Not only healthy people, but also patients with cardiovascular and cerebrovascular diseases should not routinely take oxygen without hypoxia. In this regard, a number of studies have been conducted abroad, and the results show that as long as the oxygen saturation is more than 94% (an index reflecting whether there is hypoxia in the blood), routine oxygen inhalation will not be beneficial or even harmful to patients with myocardial infarction or cerebral infarction.
Unless you are in an anoxic environment (such as plateau area and special working environment), or suffer from respiratory diseases, anemia and other diseases that lead to hypoxia of tissues and organs, oxygen inhalation for no reason is not only unhealthy, but also harmful.
