Pneumoconiosis is known as the most serious occupational disease in China, what is pneumoconiosis?

Recently, there is a piece of news that has aroused heated discussions among netizens, that is, pneumoconiosis is known as the most serious occupational disease in China, so what is pneumoconiosis? Let's talk about it today. <>

The word "pneumoconiosis" is a systemic disease mainly caused by diffuse fibrosis of lung tissue caused by long-term inhalation of productive dust or dust and retention in the lungs during work activities. And because of the different types of dust inhaled, this disease can also be divided into inorganic pneumoconiosis or organic pneumoconiosis. <>

Pneumoconiosis caused by inhalation of inorganic dust during work activities is called inorganic pneumoconiosis, and pneumoconiosis caused by inhalation of organic pneumoconiosis is called organic pneumoconiosis.

At present, there are 12 kinds of pneumoconiosis in China, including coal workers' pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis potters, pneumoconiosis journey fees, electric welding engineering fees, talc pneumoconiosis, electric grinding pneumoconiosis, carbon ink pneumoconiosis and so on.

In fact, the first grade of pneumoconiosis is very simple, mainly because there are very few simple dusts in the production environment of work, usually because of the existence of a variety of dusts, so there is a joint effect.

Moreover, the individual factors and physical condition of workers also have a certain effect on the occurrence of pneumoconiosis, the higher the content of free silica in the dust, the shorter the onset time, and the more serious the lesion.

Generally, people with pneumoconiosis will not have special clinical manifestations, but there are many mild symptoms, such as cough in the early stage of pneumoconiosis patients cough more, but it is not very obvious, with the progress of the disease, many patients will become chronic bronchitis, and advanced patients may have lung infection, and will become significantly worse cough, cough is also related to the season and climate.

In addition, patients with pneumoconiosis will also cough up sputum, which is caused by the continuous removal of dust by the respiratory system, but the amount of sputum is generally not much, and it is generally gray and thin sputum, if there is an infection in the lungs and chronic bronchitis, then the production will increase significantly, and the sputum is yellow and viscous. <>

As the fibrosis of the lung tissue increases, the effective breathing area decreases, and the ventilation ratio is out of balance, and the dyspnea gradually increases.

In addition, a small number of patients with pneumoconiosis will cough up blood, of course, this situation is relatively rare, but due to long-term chronic inflammation of the respiratory tract caused by mucosal vascular damage, there will be a small amount of blood streaks in the dish.

Respiratory system infection is mainly caused by infection inside the lungs, which is also the most common complication of pneumoconiosis patients, and a small number of people will also have spontaneous pneumothorax, because the lung tissue and visceral pleura rupture air enters the pleura, forming pneumothorax, which is also divided into three types: tension pneumothorax, non-closed pneumothorax, and communicating pneumothorax.

Pneumoconiosis is also known as pulmonary nodular disease, the patient's lungs are fibrosis, unable to normal oxygen, and finally suffocate to death.

Pneumoconiosis is the damage caused to the body by inhaling a large amount of dust powder and other objects in the respiratory tract due to the working environment when people are working.

Pneumoconiosis is a type of respiratory disease that occurs when patients work in a dusty environment for a long time, resulting in dust inhalation into the lungs.

A kind of lung disease caused by inhalation of mineral dust, the symptoms are cough, phlegm, shortness of breath, once this disease is irreversible, it will cause great damage to the lungs and fibrosis.

The air in the area where you live is dense with fine dust, which is easy to inhale into the human body, and long-term exposure to this environment will increase the pressure on the lung function.

Pneumoconiosis is caused by inhaling too much dust and harmful substances in life, causing problems in the respiratory tract and making the lungs unhealthy.

Pneumoconiosis refers to a disease in which people often work in places filled with a lot of dust, causing dust to be inhaled into the lungs, destroying the lungs and causing pulmonary fibrosclerosis.

Because the lungs inhale a lot of pollutants, these pollutants make the lungs very damaged and cause problems in people's daily lives.

1. Occupational pneumoconiosis and other respiratory diseases. Occupational pneumoconiosis, such as silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, etc.; Other respiratory diseases such as hypersensitivity pneumonitis, cotton dust disease, asthma, etc.

2. Occupational diseases. Such as contact dermatitis, photocontact dermatitis, acne, etc.

3. Occupational eye disease. There are chemical eye burns, electro-optic ophthalmia, cataracts.

4. Occupational otolaryngology and oral diseases. Such as noise deafness, chromium nose disease, knock deafness, etc.

5. Occupational chemical poisoning. Such as lead and its compounds poisoning, mercury and its compounds poisoning, manganese and its compounds poisoning, cadmium and its compounds poisoning.

6. Occupational diseases caused by physical factors. Such as heat stroke, frostbite, etc. 1, occupational pneumoconiosis and other respiratory diseases. Occupational pneumoconiosis, such as silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, etc.; Other respiratory diseases such as hypersensitivity pneumonitis, cotton dust disease, asthma, etc.

China's current "Classification and Catalogue of Occupational Diseases" stipulates that there are 13 kinds of pneumoconiosis, namely:

1.Silicosis. 2.Coal workers' pneumoconiosis.

3.Graphitus pneumoconiosis.

4.Carbon black pneumoconiosis.

5.Asbestosis.

6.Talc pneumoconiosis.

7.Cement pneumoconiosis.

8.Mica pneumoconiosis.

9.Potter's pneumoconiosis.

10.Aluminum pneumoconiosis.

11.Welder pneumoconiosis.

12.Caster's pneumoconiosis.

13.Other pneumoconiosis that can be diagnosed according to the "Diagnostic Criteria for Pneumoconiosis" and "Diagnostic Criteria for Pneumoconiosis Pathology".

2 types, inorganic pneumoconiosis and organic pneumoconiosis.

Pneumoconiosis caused by inhalation of inorganic dust during production labor is called inorganic pneumoconiosis. Pneumoconiosis is mostly inorganic pneumoconiosis. Pneumoconiosis caused by inhalation of organic dust is called organic pneumoconiosis, such as asbestosis, farmer's lung, etc.

Its clinical manifestations:

1. Cough. The cough of patients with pneumoconiosis in the early stage is not obvious, but with the progression of the disease, patients are more likely to have chronic bronchitis, and patients in the advanced stage are more likely to have lung infection, which can significantly aggravate the cough. Cough is related to the season, climate, etc.

2. Coughing up phlegm. Sputum production is mainly caused by the continuous removal of dust by the respiratory system. Generally, the amount of sputum is not much, and most of it is gray thin sputum. If there is a combination of pulmonary infection and chronic bronchitis, the amount of sputum increases significantly, and the sputum is yellow and thick or lumpy, and it is often difficult to cough up.

3. Chest pain. Patients with pneumoconiosis often experience chest pain, which is often unrelated or parallel to the clinical manifestations of pneumoconiosis. The location is different and often varied, and most of them are limited. It is generally a dull pain, but it can also be a swelling pain, pins and needles pain, etc.

4. Difficulty breathing.

With the aggravation of the degree of fibrosis of the lung tissue, the effective breathing area decreases, the proportion of ventilation and blood flow is out of balance, and the dyspnea gradually increases. The occurrence of comorbidities can significantly increase the degree and rate of dyspnea.
