Abstract: Objective  To investigate the effects of exercise breathing exercise rehabilitation therapy on lung function, exercise endurance and quality of life in patients with stable chronic obstructive pulmonary disease. Methods  80 patients with rstable chronic obstructive pulmonary disease were selected as the research objects, and they were randomly divided into an experimental group and a control group, with 40 cases in each group. The experimental group was added to the control group, and the respiratory exercise rehabilitation therapy intervention. The difference in lung function (FEV1, FVC, FEV1∶FVC) between the two groups of patients before treatment and one month after treatment was compared. The difference in quality of life (CAT score) and exercise endurance (6MWT distance) between the two groups at discharge and at 3 months after discharge was also compared. Results  After 1 month of treatment, the FEV1, FVC, FEV1∶FVC values of the experimental group were higher than those of the control group; both at the time of discharge or 3 months after discharge, the CAT values of the experimental group were lower than those of the control group, and the 6MWT values were higher than those of the control group.Conclusion Rehabilitation therapy intervention of breathing exercise exercise has a good effect on enhancing the lung function of patients with chronic obstructive pulmonary disease in stable stage, improving their exercise endurance, and improving the quality of life of patients.
