呼吸肌功能锻炼对慢性阻塞性肺疾病康复期患者的效果及肺功能的影响

Effect of respiratory muscle exercise on rehabilitation of patients with chronic obstructive pulmonary disease and its influence on pulmonary function

目的探讨慢性阻塞性肺疾病(COPD)康复期患者行呼吸肌功能锻炼后肺功能的变化。方法将我院收治的97例COPD康复期患者按随机数字表法分为对照组和观察组,对照组48例采用药物治疗,观察组49例在药物治疗的同时联合呼吸肌功能锻炼,观察比较两组患者治疗后的肺功能、血气分析水平的变化情况。结果观察组的治疗总有效率为79.59%高于对照组的60.42%,差异有统计学意义(P<0.05);观察组治疗后的FEV1、FEVl/FVC、MMEF及VCmax指标水平均高于对照组,pH、PaO_2水平高于对照组,PaCO_2水平低于对照组,差异均有统计学意义(P<0.05)。结论 COPD康复期患者行呼吸肌功能锻炼能显著改善缺氧状态,去除症状体征,促进肺功能的恢复。

Objective To investigate the changes of pulmonary function in patients with chronic obstructive pulmonary disease（COPD）in rehabilitation stage after respiratory muscle exercise. Methods 97 cases of COPD rehabilitation patients were divided into two groups,48 cases in the control group were treated with drugs,and 49 cases in the observation group were treated with respiratory muscle exercise.The changes of pulmonary function and blood gas analysis were compared between the two groups after treatment. Results The total effective rate of the observation group was 79.59%,higher than that of the control group 60.42%（P〈0.05）;after treatment,the levels of FEV1,FEVl/FVC,MMEF and VCmax in the observation group were higher than those in the control group（P〈0.05）;after treatment,the levels of pH and PaO2 in the observation group were higher than those in the control group,and the level of PaCO2 in the observation group was lower than that in the control group（P〈0.05）. Conclusion Respiratory muscle exercise can significantly improve the hypoxia status of patients with COPD rehabilitation,remove symptoms and signs,and promote the recovery of lung function.
