The survival time for pulmonary fibrosis in a 70-year-old person generally ranges from a few years to a few decades, and is mainly related to the severity of the fibrosis, as well as the patient’s treatment. If the lung fibrosis is relatively limited, the patient’s lung function is not affected, and at the same time, the standardized management is done well, and the primary cause of the disease can be removed, this situation indicates that the lung damage is relatively small, and generally does not have a great impact on life expectancy. If the area of pulmonary fibrosis is relatively large, and even shortness of breath, dyspnea, etc., or the primary cause of the disease can not be removed, and the patient did not do a good job of standardized management, then it indicates that the lung function is significantly impaired, the condition is more serious, and the life expectancy of the survival will be greatly reduced. When the discovery of pulmonary fibrosis, should promptly go to the hospital for standardized treatment, usually to maintain good living habits, avoid smoking.
