Abstract:
Objective To investigate the clinical effect of respiratory trainer in the patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) undergoing non-invasive positive pressure ven-tilation.Methods A total of 85 patients with COPD undergoing non-invasive positive pressure ventilation ad-mitted and treated in the Affiliated Minda Hospital of Hubei Nationalities University during 2019-2023 were selected as the study subjects and divided into the experiment group and the control group through random number table method.The control group adopted the symptomatic and supportive treatment such as routine non-invasive positive pressure ventilation,anti-infection,preparation aspiration for spasmolysis and eliminating phlegm,while on the base of the control group,the experiment group adopted respiratory trainer (K5) for re-spiratory training each once in the morning and at night.The differences in the related indexes were compared between the two groups.Results The percentage of forced expiratory volume in the first second (FEV1％),forced expiratory volume in 1 second/forced lung capacity (FEV1/FVC),COPD assessment test (CAT) score,modified Medical Research Council Dyspnea Scale (mMRC) score,6-min walking distance (6MWD),SGRQ score,maximum inspiratory pressure (MIP),maximum expiratory pressure (MEP),partial pressure of carbon dioxide (PaCO2) and PaO2 on 3,7 d after treatment in both groups had statistically significant differ-ence compared with before treatment (P<0.05),and the improvement of the above indicators in the experi-ment group was more significant compared with the control group (P<0.05).Conclusion Respiratory train-er could improve the clinical effect and pulmonary ventilation function in the patients with acute exacerbation of COPD undergoing non-invasive positive pressure ventilation.
