To assess the relationship between peak oxygen consumption( PVO2 ) and the ambulation distance in six-minute walk test (6MWT)among the healthy subjects.Methods The 51 healthy subjects were recruited for the six-minute walk test.Data of pulmonary gas exchange breath by breath,such as VO2,VCO2 were real-time measured with wireless remote sensing K4B2,so to study the relationship between peak oxygen uptake and the ambulation distance.Results It was noticed that there was a positive linear correlation between the ambulation distance and PVO2 ( r =0.619,P ＜0.001 ) in six-minute walk test.The regression equation was set up (VO2/kg =0.05D-6.331,P ＜0.001 ).PVO2 ＞ PVCO2 ,R ＜ 1 were found,which suggested that 6MWT was a test below anaerobic threshold.Conclusions There was a closely positive linear correlation between the ambulation distance and PVO2,which is safety,convenient and valuable for the evaluation of cardiopulmonary function and the treatment of cardiopulmonary rehabilitation.
