In general, restrictive emphysema does not affect a patient’s life expectancy. The survival time of a patient after quitting smoking is related to the patient’s age and the severity of the disease. If the patient is relatively young and does not have any serious symptoms, the survival time may be the same as normal; if the patient is older and the disease is more serious, the survival time may be relatively shorter. Confined emphysema is a type of emphysema, which refers to localized lesions in the lobes of the lungs caused by recurrent chronic inflammation, and can be manifested as emphysematous changes in one side of the lung segment or a single lobe, or in several lobes or segments of the lung. Patients with restrictive emphysema may experience symptoms such as coughing, sputum, wheezing, and dyspnea. In general, restrictive emphysema does not affect a patient’s life expectancy. The survival time of patients after quitting smoking is related to age and severity of the disease. If the patient is young and has only limited emphysema without persistent airflow limitation or ventilation dysfunction, his/her survival time will be the same as that of a normal person through active intervention and treatment; if the patient is older or has severe disease, his/her survival time may be relatively shorter. Patients are advised to strengthen the exercise of respiratory function, do abdominal breathing more often, usually pay attention to quit smoking and alcohol, prevent colds, and stay away from occupational dust exposure. Regularly go to the hospital for follow-up, monitor lung CT and lung function, and follow the doctor’s instructions for active intervention and treatment, etc.
