Objective: To explore the effect of respiratory rehabilitation training on the quality of life of pneumoconiosis patients. Methods: 76 pneumoconiosis patients who were treated in our hospital from April 2017 to December 2019 were selected as the research object, and randomly divided into 2 groups according to the order of admission by coin tossing, 38 cases in each group. The control group carried out health knowledge education on the basis of conventional treatment, and the observation group combined with respiratory rehabilitation training on the basis of the control group to compare the quality of life and lung function of the two groups of patients. Results: After 2 months of nursing care, scores of GQOLI-74 scale and pulmonary ventilation function indexes in the observation group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Respiratory rehabilitation training can improve pulmonary ventilation function of pneumoconiosis patients, improve the quality of life of patients, has good clinical application value.
