运动中吸氧对慢性阻塞性肺疾病运动康复效果的影响

Respiratory Function Training with Oxygen Inhalation for Chronic Obstructive Pulmonary Disease

目的比较运动时吸氧与不吸氧对慢性阻塞性肺疾病(COPD)患者肺功能康复效果的影响。方法将32例肺功能Ⅱ～Ⅳ级的稳定期COPD患者分为2组,吸氧组和对照组,每组16例。两组患者分别于运动康复开始前及结束后1周内完成St.George呼吸困难问卷、基础肺功能测定、6min步行距离测定(6MWD)、运动心肺功能测定及下肢疲劳度评分(BorgScale,BS)。结果肺康复训练后,吸氧组的最大氧耗量与对照组相比上升(P<0.05),其余指标无显著性差异。结论在运动时给COPD患者补充供氧可以改善运动耐力,提高肺康复效果。

Objective To compare the effect of breathing oxygen or air on respiratory function training for chronic obstructive pulmonary disease （COPD）. Methods 32 patients with stable COPD, pulmonary function Ⅱ-Ⅳ, were divided into 2 groups： oxy gen （10males and 6 females and air （12 males and 4 females）. All the patients participated in a standardized pulmonary rehabilitation program. They were assessed with St. George respiratory questionnaire, pulmonary function test, 6-minute walking distance, car diopulmonary exercise test and Borg scale, maximal oxygen consumption （VO2 max） before and after training. Results After 8 weeks of pulmonary rehabilitation, the VO2 max in oxygen group increased compared with that of the air. Conclusion Supplying oxygen dur ing training can increase the tolerance of COPD patients.
