Under what circumstances should pneumoconiosis be examined

The groups that need early pneumoconiosis examination are: direct or indirect smoking groups, occupational groups that often inhale free silicon dioxide, groups that often inhale large amounts of dust, and groups with chronic respiratory diseases such as chronic bronchitis. when there are signs such as cough, expectoration and chest pain, they should go to the physical examination center or qualified hospital for physical examination in time. The main part of the physical examination is the lungs, and at least routine physical examination should be done.

Free silicon dioxide, all kinds of dust, smoking smoke, etc., after entering the lungs from the upper respiratory tract, will generally be mostly discharged, depending on the individual's lung capacity. Each breath will always have more or less dust, free silicon dioxide and other retained in the bronchioles and alveoli. Especially in the group of indirect smoking and excessive dust inhalation, it is difficult to expel more dust and dust mites into the bronchi and alveoli.

Pneumoconiosis pathogens, such as dust and free silica, which remain in the bronchioles and alveoli, will always be swallowed by alveolar macrophages and cleared. In fact, it is these phagocytic macrophages and adhesive dust that are difficult to remove and become the direct elements of pneumoconiosis. After the phagocytic macrophages and dust left in the pulmonary bronchitis alveoli and normal cells of the lung react chemically to form pneumoconiosis, they will continue to have chemical effects and aggravate the disease.

In the constant struggle, pneumoconiosis patients will be the first to cough, and then often associated with chronic bronchitis and other lung diseases. To the middle and late stage, it may be often complicated with pulmonary infection, the double aggravation of expectoration and cough, the alternation of glacial seasons and the echo of climate change. The correlation between chest pain and pneumoconiosis is not strong, and some patients are associated with hidden pain, different sites, bloating pain, acupuncture-like pain, and so on. When these symptoms are obvious, you should see a doctor for examination in time.
