摘要目的 观察呼吸训练对缓解期慢性阻塞性肺病(COPD)患者肺功能的影响.方法 将74例缓解期COPD患者随机分为对照组和治疗组,治疗组进行6个月呼吸训练,包括缩唇呼吸、腹式呼吸、呼吸操,对照组不进行呼吸训练.比较2组治疗前、后肺功能指标.结果 治疗组呼吸训练后肺活量(VC)、用力肺活量(FVC)、第一秒用力呼出量(FEV1)、用力呼气高峰流速(PEFR)、25%肺活量最大呼气流量(V25)增加,残气量(RV)、残气/肺总量%(RV/TLC)减低,与对照组比较,差异有统计学意义(均P<0.05),与治疗前比较,差异有统计学意义(均P<0.05).结论 呼吸训练能够改善COPD缓解期患者的肺功能.

abstractsObjective To observe the effects of respiratory training on pulmonary function in the patients with chronic obstructive pulmonary disease(COPD). Methods A total of 74 patients with COPD were recruited and randomly divided into a treatment group and a control group with 37 subjects in each.The treatment group re-ceived respiratory training including lip-contracting breathing,abdominal breathing and breathing exercises for 6 months in addition to routine medical treatment.The control group received only routine medical treatment.Pulmona-ry function was evaluated before and after treatment. Results After treatment,both groups improved in terms of all the pulmonary function measures,showing increased vital capacity(VC),forced expiratory volume after 1 s(FEVl),peak forced expiratory flow rate(PEFR),as well as forced expiratory flow at 25%of Vcmax(V25),de-creased residual volume and residual volume as a percentage of total lung capacity(RV/TCL).The difference be-tween the two groups was significant with regard to the extent of improvement. Conclusion Respiratory training can improve the pulmonary function of COPD patients.
