| 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K4B^2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 K4B2.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. |
