After successful lung replacement, generally can live for less than 1 year, 5 to 10 years and above ranges, according to their own condition, the presence of complications, etc., survival time is different, analyzed as follows: 1. Survival time is less than 1 year: the patient’s own condition is poor, cardiac function is poor, and ischemia-reperfusion injury gradually occurs after lung replacement, clinical manifestations are non-cardiogenic pulmonary edema and progressive transplant lung function damage, the transplanted lungs can’t maintain the patient’s respiratory function, and at this time, the patient’s survival may be less than 1 year. 2. Survival time is more than 5 to 10 years: patients themselves have certain compensatory ability, younger age, and there is no acute rejection reaction, infection and other complications after lung replacement, the lungs are functioning normally after lung transplantation, and patients pay attention to the effective care in their daily life, they can generally survive for more than 5 to 10 years. After the success of lung replacement, patients should regularly review the chest CT, immune function, liver and kidney function and other tests, follow the doctor’s instructions for regular use of medication, do not be negligent, so as not to affect the health, and pay attention to daily life to strengthen the diet and nutrition, enhance physical fitness, and prolong the survival time.
