Bilateral pulmonary restrictive emphysema generally does not affect life expectancy, and no special treatment is required if the patient does not have any clinical symptoms. If the patient’s lung function decreases significantly and shortness of breath occurs, inhalation of ipratropium bromide, salbutamol, tiotropium bromide can be used to calm the shortness of breath. If the patient has phlegm that cannot be coughed up, expectorant medications such as tranylcypromine, eucalyptus and acetylcysteine can be used. If the patient has symptoms of cough and fever, acute infection is considered. It is necessary to improve the blood routine, C-reactive protein, calcitoninogen, virus antibody, mycoplasma antibody and other related tests to assess the possible pathogenic microorganisms of infection and make targeted treatment.
