According to estimates by the World Health Organization (WHO), COPD is currently the fourth cause of death in the world, next to heart disease, cerebrovascular disease and acute lung infection, and tied for fourth place with AIDS, and by 2020 may rise to the third cause of death in the world .

SPO2H refers to the oxygen in the blood. The normal oxygen content of the human body is about 90%. Humans live on oxygen. After oxygen is inhaled from the lungs, it enters the blood through the capillaries and is transported by the blood to various organs or cells in the body. The higher the oxygen content in the blood, the better the human metabolism.

In daily life, more and more people use the oxygen concentrator for healthcare, because it can not only prevent diseases, but also has a good auxiliary treatment effect on many diseases in life.

Hypoxia has serious effects on our heart and brain health. Because brain tissue is particularly sensitive to oxygen, people are prone to fatigue after hypoxia. Moderate hypoxia can also cause depression, apathy, and lethargy.

The following are the symptoms that have been confirmed as hypoxia and need oxygen inhalation : feel tired frequently, insomnia, asthma, backache, chest tightness, palpitations, concentration problems, etc. Asthma, chronic bronchitis, emphysema, cor pulmonale and stroke, various cardiovascular and cerebrovascular diseases, etc.

A common symptom of patients with pneumonia infected by the new coronavirus is "decreased blood oxygen levels." Blood oxygen content and body temperature, pulse, breathing, blood pressure, and pain are called the six vital signs, but this concept is not well known to most people. What does the blood oxygen content mean? What are the effects on the human body?

What are the manifestations of chronic bronchitis? Chronic bronchitis is chronic non-specific inflammation of the trachea, bronchial mucosa and surrounding tissues. Cough and sputum are the main symptoms. Chronic bronchitis has a higher incidence in middle-aged and elderly people, and patients may have continuous cough for several months. It is also prone to complications such as heart disease, pneumonia, and emphysema.

Patients who got Chronic obstructive pulmonary disease (called COPD) are prone to long-term hypoxia due to various reasons. Hypoxia can cause varying degrees of harm to the body, including increased pulmonary vascular resistance, pulmonary hypertension, chronic cor pulmonale, heart failure, red blood cells, increased blood viscosity and malnutrition.

Oxygen cylinder is the earliest oxygen supply equipment, which is not affected by power outages, but long-term using costs high and it is difficult for the transportation, meantime there are certain safety risks.

Most diseases start from hypoxia. In our country, more than half of middle-aged and elderly people, pregnant women, and students have symptoms of hypoxia; 70% of office workers are in a sub-health state, and most sub-health is essentially hypoxia.

During a bronchial asthma attack, due to bronchial smooth muscle spasm, mucosal edema, and increased secretions, the formation of the trachea is incompletely blocked. When inhaling, the inspiratory muscles contract, the thorax expands, and the air can enter the alveoli; when exhaling, the trachea collapses. The airway resistance is further increased, and the air in the alveoli cannot be fully discharged, causing the entire lung to gradually expand.

HYPOXIA CAUSE DISEASE Most people think that there isn’t a problem of shortage of oxygen in daily life. In fact, as long as hypoxia, not only it produces a lot of free radicals, but also reduce the vitality of cells. With the addition of poorly metabolized acid waste, it is no wonder that hypoxia will not only accelerate Aging can also cause terrible cancers. It can be said to be an aging killer that often accompanies you and me.
