| Objective: To investigate the application and efficacy of respiratory rehabilitation training with respiratory trainer on pulmonary function, arterial blood gas analysis, exercise activity, clinical symptoms, and quality of life in patients with stable chronic obstructive pulmonary disease (COPD). Methods: Totally, 80 patients with COPD from January 2020 to June 2020 were selected at the Department of Respiratory Medicine, Jiangsu Shengze Hospital, Nanjing Medical University. They were randomly divided into the control group and the intervention group, 40 cases in each group. In addition to conventional drug treatment, the control group received routine respiratory training (lip and abdomen breathing); the intervention group received respiratory training with respiratory trainer. The lung function, arterial blood gas analysis, exercise activity, clinical symptoms, and quality of life were compared between two groups before and after the intervention. Results: Compared with those before training, FEV1%, FVC, FEV1/FVC, PaO2, SaO2, and 6MWD in the two groups increased significantly after training (P<0.05); PaCO2, mMRC score, CAT score, and the frequency of acute exacerbations in one year decreased significantly after training (P<0.05). Compared with the control group, the indexes in the intervention group were significantly improved (P<0.05). Conclusion: The respiratory rehabilitation training following respiratory trainer is helpful to improve the pulmonary function and arterial blood gas-related indexes in patients with stable COPD, enhance exercise activity, relieve clinical symptoms, increase the quality of life, and reduce the risk of acute exacerbation, which is worthy of application in clinic and community. |
