The life expectancy of patients with pulmonary alveoli depends largely on the specific condition and cannot be generalized. In general, pulmonary alveoli do not affect the life expectancy of patients. The disease is usually secondary to chronic bronchitis and is usually associated with chronic airway inflammation caused by long-term smoking or long-term exposure to harmful gases or particles. After the appearance of pulmonary alveoli, if patients give early and timely intervention, such as actively quit smoking, strengthen physical exercise, prevent colds, and at the same time pay attention to not coughing hard, do not hold their breath, do not cause rupture of pulmonary alveoli, generally can significantly delay the progress of the disease, does not affect the life expectancy of patients, patients can survive for a long time. If the disease is not controlled, resulting in multiple pulmonary alveoli or repeated rupture of pulmonary alveoli, causing pneumothorax, sudden chest pain and dyspnea symptoms can occur, at this time, closed chest drainage should be performed in a timely manner, the patient’s prognosis is better, and will not significantly affect life expectancy. However, if the patient has a history of chronic bronchitis and is older, the formation of pneumothorax may lead to secondary infection and later respiratory failure and pulmonary heart disease, which may endanger the patient’s life in case of acute exacerbation. Patients are advised to pay attention to breathing action in daily life not to be too violent or too fast, but to inhale slowly and exhale deeply, not to smoke, and to prevent pulmonary alveoli.
