摘要
目的:评价健康受试者6min步行试验(6MWT)中峰值摄氧量(peak VO2,PVO2)与步行距离的关系。方法:对51例健康受试者进行6min步行试验,同时采用无线遥测便携式K4B2气体分析仪实时测量每次呼吸的VO2、VCO2等气体交换参数。结果:6MWT的步行距离与PVO2呈线性相关(r=0.619,P<0.001),回归方程VO2/kg=0.05D-6.331(P<0.001)。PVO2>PVCO2,R<1,提示6MWT为无氧阈以下的运动试验。结论:6MWT步行距离与PVO2密切相关,此方法安全简便,对于评价心肺功能以及评估心肺康复治疗疗效有很好的应用价值。
Objective： To assess the relationship between peak oxygen uptake （PVO2） and ambulation distance in six-minute walk test （6MWT） among the healthy subjects. Method： Fifty one healthy subjects were recruited for. Data of pulmonary gas exchange in breathing, such as VO2, VCO2 were real-time measured with wireless remote sensing K4B^2. Result： It was noticed there was a positive linear correlation between the ambulation distance and PVO2 （r=0.619, P〈0.001） in 6MWT. The regression equation was set up （VO2/kg =0.05D-6.331, P〈0.001）. PVO2〉 PVCO2,R〈1 were found,which suggested 6MWT was a test under anaerobic threshold. Conclusion： There was a closely positive linear correlation between the ambulation distance and PVO2 in 6MWT, which is safe, convenient and valuable for the evaluation of cardiopulmonary function.
