主　　题：six-minute walk test oxygen consumption(PVO2) cardiopulmonary function 

摘      要：Objectives 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.
