With the continuous improvement and improvement of people’s living standards and the increasing demand for health, oxygen inhalation will gradually become an important means of family and community rehabilitation. However, many patients and oxygen users do not have enough knowledge of oxygen inhalation, and oxygen therapy is not standardized. Therefore, who needs oxygen and how to perform oxygen inhalation is the knowledge that every patient and oxygen user must understand.
1. Hypoxia hazards of Oxygen Generator
The hazards and important manifestations of hypoxia on the human body Under normal circumstances, hypoxia has the following main hazards to the human body: during hypoxia, the aerobic metabolism rate in the human body decreases, anaerobic glycolysis is strengthened, and the body’s metabolic efficiency decreases; long-term severe hypoxia can cause Pulmonary vasoconstriction causes pulmonary hypertension and increases the burden on the right ventricle, which can cause pulmonary heart disease in the long run; hypoxia can aggravate high blood pressure, increase the burden on the left heart, and even cause arrhythmia; hypoxia stimulates the kidneys to produce erythropoietin, which makes the body Red blood cells increase, blood viscosity is high, peripheral vascular resistance increases, heart burden increases, causing or aggravating heart failure, and it is easy to induce cerebral thrombosis; long-term hypoxia in the brain can produce a series of mental and neurological symptoms: such as sleep disorders, decreased intelligence, Memory decline, abnormal behavior, personality changes, etc. Usually, people’s hypoxia has the following important manifestations: increased breathing frequency, dyspnea, chest tightness, suffocation of breath, cyanosis of the lips and nail bed; rapid heartbeat; due to increased anaerobic glycolysis, the level of lactic acid in the body rises, often fatigue and fatigue Feelings of illness; lack of concentration, decreased judgment and memory; night sleep disturbance, decreased sleep quality, sleepiness during the day, dizziness, headache and other symptoms.
2. Oxygen inhalation of Oxygen Generator
The conditions and advantages of oxygen inhalation oxygen inhalation is sometimes called “oxygen therapy”. Although it cannot cure all diseases, it does have obvious effects on some diseases. It can not only supply oxygen to hypoxic tissues, but also dissolve blood. The air bubbles stimulate wound healing, as well as air bubble embolism, carbon monoxide poisoning, cyanide poisoning, unhealed wounds, bone injury and necrosis, soft tissue infection, cerebral edema and other diseases. Supplying oxygen to premature babies and people with serious illnesses or injuries under normal pressure is also an important measure to save lives. It can be considered that not only patients with hypoxia need to inhale oxygen, but normal people also need to replenish a certain amount of oxygen in the natural environment. Such as patients with coronary heart disease, pulmonary heart disease, asthma, bronchitis, and various cardiovascular and cerebrovascular chronic diseases, pregnant women, mental workers with stressful work and study, elementary schools, junior high schools, high schools, universities, graduate students and other test preparation personnel, plateau hypoxic areas Residents, tourists, etc.
3. Oxygen therapy of Oxygen Generator
According to many literature reports, the main points are summarized as follows: relieve nervous fatigue, relax the body and mind, maintain vigorous energy, and improve work efficiency; improve the oxygen supply of the brain, regulate the function of the cranial nervous system, improve memory and thinking ability, and improve learning efficiency; Reduce the harm to the body under pollution and harsh environments; to a certain extent, it can delay aging and enhance metabolism; reduce hypoxemia and meet the needs of tissue metabolism; relieve pulmonary hypertension caused by hypoxia, reduce polycythemia, and reduce blood viscosity It can reduce the burden on the right ventricle and delay the occurrence and development of cor pulmonale; oxygen inhalation can relieve bronchospasm, reduce breathing difficulties, and improve ventilation dysfunction; improve the patient’s physical and brain function, improve exercise endurance and quality of life; improve chronic obstructive pulmonary disease , Prolong life; reduce the number of hospitalizations, save medical costs; can reduce post-operative infections and antiemetics.
Generally, people who meet any of the following three items should be treated with long-term home oxygen therapy: ① The clinical state is stable for 3 to 4 weeks, without acute bronchitis, lung inflammation, heart failure, and 2 consecutive 2 weeks arterial blood gas analysis results: arterial blood oxygen Partial pressure PaO2<60mmHg, blood oxygen saturation SaO2<88%. ② The clinical state is stable, and the results of at least two arterial blood gas analyses: The partial pressure of arterial oxygen PaO2 is 55-59mmHg, accompanied by secondary red blood cell hypertension, pulmonary hypertension or pulmonary heart disease, right heart failure, and PaO2 drops by 10mmHg after exercise One. ③ PaO2>55mmHg during the day, but SaO2<75% at night or severe sleep apnea. It should be noted that oxygen therapy for patients with chronic obstructive pulmonary disease (COPD) has gradually been paid more attention. Patients with COPD have dysfunction and ventilation due to long-term ventilatory dysfunction. Imbalance of blood flow leads to lack of O2 and CO2 retention, especially nocturnal hypoxemia is more serious.
