Stage II pneumoconiosis cannot be cured, but symptoms can be relieved and disease progression can be slowed down through the use of medications (salmeterol aerosol, aminophylline, etc.), rational oxygen therapy, and active treatment of complications/comorbidities under the guidance of a doctor. 1. Pharmacotherapy: Under doctor’s supervision, β₂ agonists, such as salbutamol aerosol, salmeterol aerosol, etc., can be used to increase cyclic adenosine, which can relax the smooth muscles of the airway; theophyllines, such as aminophylline, doxophylline, etc., which can have anti-inflammatory and immune-modulating effects; and cough suppressants, such as codeine, dextromethorphan, and nalcodone, etc. can also be used. 2. Reasonable oxygen therapy: increase the concentration of inhaled oxygen, increase the partial pressure of alveolar oxygen, increase the difference in partial pressure between the two sides of the alveolar membrane, promote the diffusion of oxygen, increase the partial pressure of arterial oxygen and oxygen saturation, and improve the supply of oxygen to the organs of the whole body. 3. Active treatment of complications/complications: Pneumoconiosis can be combined with respiratory infections, tuberculosis, COPD, pneumothorax, COPD, COPD, COPD, etc. It is necessary to actively treat the complications/complications to improve the patient’s symptoms and slow down the progress of the disease. It is recommended that patients go to regular hospitals, under the diagnosis of the doctor, according to the patient’s specific condition performance, to take targeted treatment. Life should quit smoking, avoid living dust contact, strengthen nutrition and develop healthy and good living habits.
