Lung dysfunction
Introduction
Introduction The lungs maintain the physiological characteristics of the hair and the descending, and can complete the physiological functions of the main gas, the water and the main rule. If the lungs have qi stagnation, the gas or the gas will affect the function of the lungs and cause pulmonary dysfunction. .
Cause
Cause
1. Physiological aging
With the increase of age, the wall hardness of the elderly increases, the elastic retraction force of the lung decreases, and the rebound tension decreases, which causes the lung capacity to decrease progressively. Changes in the lungs and chest wall can cause changes in lung ventilation in the elderly, leading to an imbalance in lung ventilation or blood flow, increased airway resistance, increased collagen content in the alveolar wall, and reduced effective area of the respiratory membrane for maximum ventilation. It gradually decreases with age. At the age of 60, it may fall to half of the original level, and the amount of residual gas gradually increases. In addition, due to the reduction of alveolar area and emphysema in the elderly, it is also easy to cause hypoxia in the lungs.
2. Environmental pollution
Because our lungs are directly connected to the outside world, harmful substances such as microorganisms, dust, allergens and harmful gases are easily absorbed into the lungs and cause various injuries; in addition, the weak mucosal tissue structure in the lungs has poor anti-invasive ability. And its warm and humid environment is most conducive to the survival of bacteria and viruses, so that the lungs will be affected by various kinds of pollution, affecting lung function.
3, lung disease
The most important cause of lung dysfunction in the elderly is lung disease, in which chronic obstructive pulmonary disease (KD) is a common disease in the elderly. Chronic obstructive pulmonary disease is a group of diseases with airway obstruction. It is actually a general term for diseases such as chronic bronchitis and emphysema. Suffering from this disease, there will be more and more "garbage" in the lungs. "Lung garbage" is what we know as "". The long-term accumulation of cockroaches can not be removed in time, blocking our breathing passages, fresh air (oxygen) can not come in, the exhaust gas produced by the body metabolism can not be discharged, resulting in a decline in lung function, resulting in hypoxia.

Diagnosis
Differential diagnosis
Diseases should be detected early and treated early. Because lung function is not easy to observe, it will be discovered when it is severe. This often misses the best time for treatment. Therefore, regular physical examination is very necessary. If you are a long-term smoker, you should check your lung function regularly. There are people who have repeated coughs, shortness of breath, chest tightness, people who are exposed to pollutants every day, people with respiratory diseases, etc., should regularly do a lung function test, which is a manifestation of the person in charge of physical health.
