呼吸训练和促进有效排痰应用于急性加重期慢性阻塞性肺疾病患者的效果观察

目的探讨呼吸训练和促进有效排痰对慢性阻塞性肺疾病（COPD）急性加重期患者康复的影响。方法将50例患者随机分成干预组和对照组各25例，干预组由护士进行呼吸训练和促进有效排痰，对照组按常规进行治疗护理，比较2组患者第1秒用力呼气容积占用力肺活量百分比、氧分压、二氧化碳分压、血氧饱和度及2组患者住院天数。结果干预组肺功能各项指标显著优于对照组，P〈0．05，住院天数缩短，P〈0．01。结论呼吸训练和促进有效排痰对COPD急性加重期患者康复有较好的效果。

Respiratory training and prompting effective discharging of sputum for COPD patients in acute aggravation period

Objective To discuss the influence of respiratory training and prompting effective discharging of sputum for chronic obstructive pulmonary disease （COPD） patients in acute aggravation period. Methods 50 patients were randomized into the intervention group and the control group with 25 cases in each group.The intervention group received respiratory training and prompting effective discharging of sputum while the control was only given routine treatment and nursing.The ratio of first second expiration volume to forced vital capacity, oxygen partial pressure （PaO2）,carbon dioxide partial pressure （PaCO2） , blood oxygen saturation （SpO2）and the in-hospital days were compared between the two groups. Results The clinical effect in the intervention group was superior to that of the control group with shorter in-hospital days （P 〈0.01）. Conclusion Better results could be obtained by application of respiratory training and prompting effective discharging of sputum for COPD patients in acute aggravation period.
