Oxygen generator mainly uses oxygen supply to improve the physiological and biochemical internal environment of the human body, and promote a virtuous cycle of metabolic processes, so as to achieve the purpose of treating diseases, relieving symptoms, promoting recovery, preventing lesions, and improving health. Clinical practice has proved that oxygen therapy, with its unique treatment mechanism, can effectively treat acute and chronic ischemia-hypoxic disorders and secondary diseases caused by hypoxia in various clinical departments.

Proper oxygen inhalation can also improve microcirculation, reduce the respiratory system load necessary to maintain a certain alveolar gas partial pressure of oxygen, and reduce the myocardial load necessary to maintain a certain arterial blood oxygen partial pressure. Therefore, in clinical medicine, preventive medicine, emergency medicine, geriatric medicine, rehabilitation and health care medicine, oxygen therapy and oxygen health care have irreplaceable important roles and broad development prospects.

When the human body is hypoxic or is about to be hypoxic, oxygen is given to increase the oxygen concentration of the inhaled gas, increase the oxygen content of the arterial blood, and improve the oxygen supply of the tissues, collectively referred to as oxygen therapy. Generally speaking, it is used to correct pathological hypoxia as an auxiliary treatment method for diseases, called oxygen therapy; among them, it is used for critically ill patients and accident victims, called oxygen first aid; it is used to supplement heavy mental workers, elderly people Physiological hypoxia of people, pregnant women and patients in the rehabilitation period of chronic diseases, as well as supplementing various environmental hypoxia, as the prevention of hypoxia, is called oxygen health care.

Compared with other medical methods and health care methods, oxygen therapy and oxygen health care are active, direct, fast and safe means. Its characteristics are: oxygen inhalation directly increases the oxygen content of arterial blood, rather than acting on a certain part of the body to indirectly improve hypoxia; it only increases the oxygen that the body has been ingesting throughout life, and there is no unfamiliar to the body, need to adapt, need Therefore, it only improves rather than changes the body's natural physiological state and biochemical environment; low-flow oxygen therapy and oxygen health care, without special guidance, the effect is fast and certain, beneficial and harmless.

Oxygen therapy has the effect of relieving hypoxia symptoms in a timely manner, but it has only a partial and gradual effect on eliminating the causes of hypoxia. Oxygen therapy is the main means for correcting physiological hypoxia and environmental hypoxia and preventing and treating diseases caused by environmental hypoxia. For correcting pathological hypoxia, oxygen therapy is an important auxiliary means. For emergency rescue, oxygen therapy is one of the most important means. Therefore, anyone who need oxygen therapy should adhere to a longer course of treatment, and perseverance can consolidate the curative effect.

While carrying out oxygen therapy, we must not ignore the timely diagnosis of the cause; we must not ignore taking symptomatic drugs as prescribed by the doctor; we must not ignore the treatment of complications of hypoxia; we must also strengthen aerobic physical exercise to enhance our ability to absorb, transport and utilize oxygen.
