| Objective: To explore the impact of a three ball breathing trainer and airway clearance technology on the rehabilitation effect of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: All 102 AECOPD patients were selected as the study subjects. They were randomly divided into an observation group (treated with a triple ball breathing trainer combined with airway clearance technology) and a control group (treated with airway clearance technology) using a random number table method, with 51 patients in each group. The sputum volume, sputum color score, mucus viscosity, percentage of forced expiratory volume in the first second (FEV1% predicted value), percentage of maximum ventilation volume per minute (MVV%pred), FEV1/FVC, peak airway pressure, respiratory pressure, and airway resistance were compared between the two groups. Results: After intervention, sputum volume and sputum color score in 2 groups were significantly lower than before intervention (P<0.05). Compared with control group, sputum volume and sputum color score in the observation group were significantly decreased after intervention (P<0.05). After intervention, the viscosity of the two groups was significantly improved as compared with that before intervention (P<0.05). Compared with the control group, the improvement degree of mucous consistency in the observation group was better than that in the control group (P<0.05). Multiple measurement ANOVA showed that the predicted value of FEV1%, MVV%pred and FEV1/FVC in the two groups had time, inter-group and inter-group interactions, and the differences were statistically significant (P<0.05). The predicted value of FEV1 (%), MVV%pred and FEV1/FVC in the 2 groups were significantly higher than those before, and 7 and 14 days after intervention (P<0.05). Compared with the control group, FEV1 predicted value (%), MVV%pred and FEV1/FVC in the observation group were significantly higher than those in the control group (P<0.05). Repeated measurement ANOVA showed that the time, intergroup and intergroup interaction of peak airway pressure, respiratory pressure and airway resistance of the 2 groups were statistically significant (P<0.05). After 7 and 14 days of intervention, the peak airway pressure, respiratory pressure and airway resistance of the 2 groups were decreased as compared with those before intervention (P<0.05). Compared with the control group, the peak airway pressure, respiratory pressure and airway resistance in the observation group were significantly reduced (P<0.05). Conclusion: The combination of a three ball breathing trainer and airway clearance technique is beneficial for improving lung function, respiratory mechanics, and promoting sputum excretion in AECOPD patients. |
