【摘要】 目的探讨老年慢性阻塞性肺疾病(COPD)患者运动肺功能试验的特点。方法随机抽取稳定期COPD患者22例,按照年龄分为老年组和对照组,分别进行静态肺功能和运动肺功能测定。结果老年组和对照组的静态肺功能无显著性差异(P>0.05),老年组的最大运动功率、最大耗氧量、最大运动时每分钟通气量均低于对照组(P<0.05),死腔通气量高于对照组(P<0.05)。结论老年COPD患者进行运动肺功能试验是安全的,而且能够反映患者的运动耐量和运动通气功能的变化。更多还原

【Abstract】 Objective To investigate the clinical manifestations in exercise pulmonary function test of the elderly patients with chronic obstructive pulmonary disease(COPD). Methods Twenty-two patients with stable COPD were divided into two groups,elderly group and control group. All patients underwent spirometry and exercise pulmonary function test. Results There were no significant differences in resting spirometric parameters between two groups(P>0.05). The maximal rate of work, maximal oxygen uptake, the maximal volume of ventilation per minute were lower in elderly group than those in control group(P<0.05), but the maximal dead space/tidal volume ratio was higher in elderly group than that in control group(P<0.05). Conclusions Exercise pulmonary function test is safe for the elderly patients with COPD.It can reflect exercise tolerance of patients and the change of ventilation during exercise.更多还原
