After asbestos is inhaled into the lungs, if part of the asbestos is inhaled for a short period of time, it will not affect the lungs greatly, but if it is inhaled into the lungs continuously for a long period of time, it will easily cause asbestosis, resulting in fibrosis, calcification or even cancerous tendency in the lungs to varying degrees. There are some ways to expel asbestos from the lungs, such as changing positions, adopting a head-down position, and having someone else pat the back to promote the discharge of secretions in the body, so that some of the asbestos in the body can be coughed out with the secretions. In addition, it is important to avoid the invasion of asbestos, to leave the place where asbestos exists in life and work, and to go to a place where the air is relatively good and fresh. If long-term inhalation has led to different degrees of fibrosis and calcification in the lungs, anti-fibrotic drugs such as kirsilpine and, if necessary, hormones such as dexamethasone, methylprednisolone, prednisone, etc., as well as the Chinese herbal medicine rehmannia can be given appropriately, and regular follow-ups can be made to prevent further development of the disease. Physical exercises such as balloon blowing and lip contraction breathing should be done to improve cardiopulmonary function and strengthen the immunity of the lungs, which can promote the discharge and metabolism of asbestos.
