Observation on the effect of blow-suction breathing training device applied to the patients with stable chronic obstructive pulmonary disease in the community
Objective To explore the practical value and safety of blow-suction breathing training device applied to the patients with stable chronic obstructive pulmonary disease(COPD)in the community.Methods A total of 90 patients with stable chronic obstructive pulmonary disease were selected.They were randomly divided into an experimental group(44 cases)and a control group(46 cases).The control group underwent routine breathing training,and the experimental group underwent breathing training with blow-suction breathing training device.Comparison was made on pulmonary function indexes[forced expiratory volume in one second as a percentage of the expected value(FEV1%pred),ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC)],6-min walking distance(6MWD),frequency of acute exacerbations and adverse events between the two groups.Results After intervention,FEV1%pred and FEV1/FVC increased in both groups compared with those before intervention;the experimental group had FEV1%pred of(66.98±10.12)%and FEV1/FVC of(59.22±9.47)%,which were higher than(58.10±5.01)%and(51.09±8.21)%in the control group;the difference was statistically significant(P<0.05).After intervention,6MWD in both groups increased compared with that before intervention,and the experimental group had longer 6MWD of(340.98±38.19)m than(322.14±38.91)m in the control group.The difference was statistically significant(P<0.05).During the follow-up period,the number of acute exacerbations was 2 person-time in the experimental group and 2 person-time in the control group,and there was no statistical significance between the groups(P>0.05).No adverse events occurred in either group.Conclusion Blow-suction breathing training device shows significant effect in the pulmonary rehabilitation treatment of patients with stable chronic obstructive pulmonary disease in the community.
