How to clean up the dust particles inhaled by the lungs?
There is a specific medicine for lung washing. Dietotherapy methods circulating in life, such as eating pig blood and removing dust with fungus, have long been proved invalid by medicine.
This is the theory of moistening lung and resolving phlegm in traditional Chinese medicine, not dust removal. Once inhaled, the dust enters the alveoli of the lungs and becomes mud, which cannot be removed unless the lungs are washed in the hospital.
There is a lot of dust in the lungs, which is easy to cause pneumoconiosis and is secondary. Pneumoconiosis is also called a disease that has no right to lie down and die. Must be highly valued. Scientific selection of dust mask is helpful to prevent respiratory tract injury. Now masks must implement GB2626-2006 standard. Dust masks are divided into KN 100, KN95 and KN90. Among them, the protective effect of KN 100 on ultrafine dust can reach nearly100% (more than 99.97%). The protective effect of dust mask depends on two aspects: one is the filtering efficiency of cotton filter screen. The second is the tightness of the mask and the face. Therefore, masks must be divided into different sizes, and the fitting effect of masks with different sizes and different faces varies from person to person. Methods of cleaning dust: scientifically selecting the dust mask certified by GB2626-2006 is helpful to prevent lung injury;
1, select the composite half mask type. Disposable masks have high air leakage rate and are not suitable for long-term protection.
2. Choose KN 100 dustproof filter cotton for use. Low protection rate will lead to physical injury.
3, the choice of silicone material is more comfortable. Suitable for long-term wear, not easy to cause allergic reactions. A mask with high hardness is easy to cause facial depression.
4. The size of the mask is extremely important. Don't buy those so-called universal masks. Easy to leak.
The mask covers the nose and mouth, and covers the nose, mouth and chin. Suggest using the latter, which is relatively comfortable.
6. It is recommended to choose a mask with smooth breathing. Some masks are designed with double filter cotton, and the filter cotton has two sides, which makes the mask breathe relatively smoothly.
