ObjectiveTo explore the influence of respiratory function training on pulmonary function of patients with pneumoconiosis. MethodsOne hundred patients with pneumoconiosis hospitalized in our department between June 2011 and September 2012 were chosen as the research subjects. According to the method of random digits table, they were equally and randomly divided into contrast group and observation group. Patients in both the two groups were given routine treatment and nursing and health education, while patients in the observation group adopted respiratory training with lung functional exerciser in addition. Then we observed the forced expiratory volume in one second (FEV1), vital capacity, maximal voluntary ventilation, forced vital capacity, classification of conscious shortness of breath and shortness of breath as well as classification of activities of daily living in the patients before and after training in both the two groups. ResultsAfter 6 months, lung function index, classification of conscious shortness of breath and shortness of breath as well as classification of activities of daily living of patients in the observation group improved a lot, which was significantly better than that in the contrast group (P<0.05). Compared with the contrast group, the FEV1 [(2.75±0.43) L], vital capacity [(3.29± 0.45)L] of patients in the observation group were significantly higher (P<0.05). Compared with the contrast group, classification of conscious shortness of breath and shortness of breath (2.10±0.67), classification of activities of daily living (2.19±0.66) were also significantly different (P<0.05). ConclusionRespiratory function training with lung functional exerciser can improve lung function of patients with pneumoconiosis, alleviate the degree of dyspnea, and enhance the quality of life.
