What causes pneumoconiosis and what causes pneumoconiosis?

Pneumoconiosis, also known as pneumoconiosis, is an occupational disease. It is more common in patients who do not take appropriate protective measures at work and inhale production dust for a long time, and the dust accumulates in the bronchial tubes and alveoli at the end of the respiratory tract, forming a barrier layer, which will affect the gas exchange between the alveoli and the outside world during breathing. Long-term pneumoconiosis patients who do not undergo ** will further lead to right ventricular hypertrophy, cor pulmonale, etc., and long-term pneumoconiosis can also induce lung cancer, emphysema and other diseases.

Mild patients only have cough, sputum and other manifestations, severe cases will lead to dyspnea, chest tightness, chest pain and other manifestations, so it is recommended that workers engaged in long-term large-scale exposure to dust must do a good job of protection, wear masks or face shields. For patients who have developed pulmonary fibrosis and severe decline in lung function, it is necessary to perform aggressively** and, if necessary, surgery**.

The simple point is that the dust is inhaled too much, such as some construction sites, there will be a lot of dust in the production workshop, inhaled into the lungs, and deposited to a certain amount of diseases caused by it.

1.Peak commuting period: The transportation is congested and the air circulation is poor, which is easy to induce occupational allergic rhinitis and occupational dermatitis. Especially on public transport, there is an increased chance of exposure to various allergens and bacteria.

2.Long-term continuous work: Long-term continuous work can easily lead to eye fatigue and computer vision syndrome. Standing for a long time can also induce varicose veins of the lower limbs, orthopedic diseases, etc.

3.Night shift or frequent adjustment of biological clock: Night shift work or frequent adjustment of biological clock can lead to sleep disorders, which in turn can lead to occupational diseases such as digestive diseases, cardiovascular diseases, endocrine diseases, and reproductive system diseases.

4.Peak work period or project deadline: high work intensity, long time and high pressure during peak work period can induce psychological and occupational diseases such as occupational diseases, acute stress disorder, occupational diseases, neurasthenia, etc. It can also cause digestive system diseases, cardiovascular diseases and other physiological and occupational diseases.

5.Specific operating processes: dust or toxic gases generated by grinding, spraying, welding and other operations can cause corresponding occupational diseases, such as occupational pulmonary fibrosis, occupational poisoning, etc.

Repetitive strain injuries of the arm also occur during these processes.

6.Special working environment: Extreme working environments such as high temperature, low temperature, high noise, and strong magnetic field will induce occupational diseases corresponding to the environment, such as altitude sickness, cold fatigue, noise deafness, etc.

7.During holidays: During holidays, some special work such as maintenance, operation, and duty should be carried out, which is more likely to induce psychological or physical occupational diseases.

Reasonable work and rest and good labor protection are the keys to preventing the onset of occupational diseases. Vigilance should be heightened at specific moments and corresponding protective measures should be taken to reduce the occurrence of occupational diseases.

Pneumoconiosis is an occupational disease, which is a disabling disease caused by inhalation of dust with a particle size of less than 5 microns due to lack of respiratory protection or improper respiratory protection during work, accompanied by various complications such as hypoxemia, and cannot be treated**.

To prevent pneumoconiosis, in addition to taking various dust prevention and dust reduction measures, the main thing is to do a good job in the respiratory protection of employees under dust, and the reasons for the frequent occurrence of pneumoconiosis at present:

1. Practitioners ignore respiratory protection and do not understand the hazards of dust.

2. Considering too many economic factors, choosing counterfeit masks as inferior masks, or simply not wearing masks, there is a fluke mentality.

3. Dust masks will not be selected scientifically, resulting in pneumoconiosis despite protection.

It is recommended to start from the following aspects to make scientific choices to prevent pneumoconiosis.

If you are engaged in high-dust work for a long time, it is recommended to use high-grade protective masks to prevent lung diseases.

1. As a special labor protection product, dust masks must be certified by GB2626-2006. Gas masks are certified according to GB2890-2009 standard.

2. Masks are divided into disposable and replaceable filter half masks and full masks. For long-term occupational protection use, it is recommended to use a replaceable filter cotton half mask.

3. The mask material is silicone, plastic, etc., the silicone material is relatively soft and comfortable, and the facial pressure is low.

4. For dust and oily particles, protective masks are divided into oil-proof (oily smoke, oil mist, dust, smoke, fog, microorganisms, represented by KP) and dust-proof (dust, smoke, fog, microorganisms). For dust prevention, there are three levels of protection level: KN100, KN95 and KN90, due to the diversity of pollutants in the working environment, the harm to people is greater, it is recommended to choose KN100 level.

5. It is particularly important that the mask is divided into sizes according to the national standard. Many masks are not semicolonized, and the effect will vary from person to person.

6. There are two types of masks: covering the mouth and nose and covering the mouth, nose and jaw, of which the second type has a large contact mask, good sealing and low pressure sensitivity.

Don't ignore respiratory protection, using fake and shoddy goods, gauze, towels, etc. as masks, which can easily lead to lung diseases. At present, some common N100 grade dust masks can breathe smoothly while ensuring the protective effect, and they are about one yuan a day, which is affordable for both enterprises and individuals.

Hello! Pneumoconiosis is a systemic disease caused by long-term inhalation of productive dust, mainly diffuse fibrosis of lung tissue, which needs to be treated in a regular hospital in a timely manner, and standardized under the guidance of a specialist doctor to delay the progression of the disease. Usually relax your mind, maintain an optimistic mood, get away from the dust working environment, pay attention to keeping warm, and prevent cold.

Pneumoconiosis is when there are dust particles in the lungs that block the lung tissue, affecting respiratory function. The symptoms are cough, sputum, backlash, chest tightness, dyspnea, etc., and the harm is to affect respiratory function, dyspnea, induce lung cancer, etc.

It is the sediment in the lungs and the feeling of breathing, which can lead to silicosis.

Silicosis is a type of pneumoconiosis and is a serious occupational disease (stone quarry workers, etc.). Free silica powder (dust in the air) dust accumulates on the alveoli of the human lungs through the respiratory tract, affecting the gas exchange, and finally the alveoli of the human body lose their function, and the lung tissue is all fibrotic. Simply put, the lungs become a lump of dirt.

The rest is the same effect as coal dust, but mainly silicosis caused by silica powder.

1. How does harmful dust cause pneumoconiosis?

The pathogenic mechanism of dust-induced pneumoconiosis has not been satisfactorily explained so far. The physical and chemical properties of various dusts are different, the effects on the body and the reactions caused are also different, the nature and severity of the lesions are also different, and the nature and degree of damage caused are also different.

2. What are the manifestations of pneumoconiosis?

Early pneumoconiosis often has no symptoms or is mild, and the presence of early pneumoconiosis can only be detected through a health examination. Patients with middle and advanced stage pneumoconiosis generally have mild or severe self-conscious symptoms, pneumoconiosis mainly invades the respiratory system, so the common early symptom of patients is shortness of breath. People with mild disease often feel short of breath when doing heavy physical work or climbing mountains, which can get better after rest.

Slightly heavier patients have significant shortness of breath when engaging in light physical labor, walking uphill or climbing stairs. When the condition is severe or there are complications, the respiratory and circulatory functions are significantly impaired, and even when you are resting or inactive, you may feel that you may not be able to breathe, and you may not even be able to sleep. In addition to shortness of breath, chest tightness, chest pain, cough, especially dry cough are more common.

There can also be phlegm, hemoptysis, weakness, weight loss, insomnia, decreased appetite, etc.

The biggest harm of pneumoconiosis is that it causes changes in the normal structure of the lungs, damages the function of the lungs, and affects the normal respiratory function of the human body. It is recommended that you go to the local vocational hospital for specialist diagnosis and treatment, actively **, delay the development of the disease, prolong life, and improve the quality of life.

Hello, pneumoconiosis is the lungs inhaled dust, deposited in the lungs, after a long time will feel chest tightness and wheezing, in addition, pneumoconiosis patients are particularly prone to infection, cough, sputum, fever, thick sputum and other symptoms. In the early stage, the cough of patients with pneumoconiosis is not obvious, but with the progression of the disease, patients with pneumoconiosis are more likely to have chronic bronchitis, and patients with advanced stage are often prone to lung infection, which makes the cough significantly aggravated. Sputum production is a common symptom and can occur in patients with pneumoconiosis even when coughing is rare, due to the constant removal of dust from the respiratory system.

Dyspnea is also an inherent symptom of pneumoconiosis, and pneumoconiosis patients have difficulty breathing and the condition is related, and with the aggravation of the degree of fibrosis of lung tissue, the effective breathing area decreases, and the dyspnea becomes more severe.

Hello, pneumoconiosis is a disabling occupational disease with no medical end. Patients with pneumoconiosis have chest tightness, chest pain, cough, sputum production, exertional dyspnea, susceptibility to colds, decreased respiratory function, which seriously affects the quality of life, and the condition will be upgraded every few years, combined with infection, and finally death from pulmonary heart disease and respiratory failure.

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

2.Coughing up sputum. Sputum production is mainly caused by the continuous removal of dust by the respiratory system. Generally, the amount of sputum produced is not large, 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 viscous or lumpy, and it is often difficult to cough up.

3.Chest pain. Patients with pneumoconiosis often feel chest pain, and chest pain and clinical manifestations of pneumoconiosis are often not related or parallel. 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.Dyspnea.

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.

5.Hemoptysis. Rarely, it can cause mucosal vascular damage due to long-term chronic inflammation of the respiratory tract, and a small amount of blood streaks in sputum; It may also increase blood volume due to the lysis and rupture of large fibrotic lesions and damage to blood vessels.

6.Other. In addition to the respiratory symptoms described above, there may be systemic symptoms of varying severity, and digestive dysfunction is common.

Early pneumoconiosis can have no symptoms at all, or it can have mild cough, sputum production, chest tightness, and wheezing. It is precisely because the symptoms of pneumoconiosis in the early stage are not obvious, so many patients do not go to the doctor in time when pneumoconiosis occurs, miss the treatment, and wait until the symptoms are obvious, often to the second and third stages. Therefore, workers who are exposed to dust must do a good job of occupational health examination, must participate in occupational health examination, and regularly check chest X-ray and lung function.
