Oxygen concentrator are a kind of machine that produces oxygen. The principle is to use air separation technology. First, the air is compressed at a high density and then the gas is separated at a certain temperature by further different condensation points of the components in the air, and further refined.
It is characterized by oxygen absorption directly increases the blood oxygen content of the arteries, rather than acting on a part of the body to improve hypoxia indirectly, but only increases the oxygen that has been continuously ingested during the lifetime of the body. There is no material that is unfamiliar to the body and needs to be adapted and needs to be resolved, thus only improving rather than changing the natural physiological state and biochemical environment of the body. Low-flow oxygen therapy and oxygen care do not require special guidance to quickly and certainly beneficial and harmless. Oxygen therapy has the effect of alleviating hypoxia symptoms in time, but only partially and progressively to eliminate the cause of hypoxia. For the correction of physiological hypoxia and environmental hypoxia, prevention and treatment of diseases caused by environmental hypoxia, oxygen therapy is the main means. Oxygen therapy is an important adjunct to correct pathological hypoxia. For emergency rescue, oxygen therapy is one of the important means.
