Lung obstruction is categorized into chronic obstructive pulmonary disease and pulmonary embolism in the clinic, and patients can be handled and treated by general treatment, medication and surgery. 1. Chronic Obstructive Pulmonary Disease (COPD): When the symptoms are mild, drugs such as ipratropium bromide and salbutamol sulfate can be used for treatment. When the disease is serious, it needs to be treated by using cephalosporin and other drugs with bronchodilators. Patients should quit smoking, stay away from polluted environments, and inhale oxygen at the same time. 2. Pulmonary embolism: patients with pulmonary embolism should be treated with anticoagulant therapy, such as warfarin, heparin and other drugs, and thrombolytic therapy, such as urokinase, streptokinase, etc., when the symptoms are serious. If the patient has varicose veins of the lower limbs and causes pulmonary embolism, if necessary, the patient needs to be treated with filter surgery at the varicose veins. Patients with pulmonary obstruction should consult the doctor in time and take active treatment so as not to miss the disease.
