Abstract |
<Summary> [Objectives] The purpose of this study is to investigate the relationship between the exercise tolerance measured by cardiopulmonary exercise testing (CPX) and the Δ Blood volume (ΔBV) during dialysis in patients with hemodialysis. [Methods] Anaerobic threshold (VO2AT) and peak oxygen uptake (VO2peak) that are indicators of exercise tolerance were measured by CPX from 20 hemodialysis patients. The slope of the regression equation of ΔBV from the start to the end of dialysis was calculated in hemodialysis session after the next week of CPX. In addition, the relationship between the slope of the regression equation of ΔBV and VO2at or VO2peak was examined by Pearson's correlation coefficient. [Results] Both VO2AT (r = 0.44) and VO2peak (r = 0.54) were significantly correlated with the slope of ΔBV (p <0.05). Result of partial correlation coefficient that fluid removal rate is control variable, VO2peak (r = 0.54) had significant correlation with the slope of ΔBV (p <0.05). [Discussion] The subjects with higher exercise tolerance had lower ΔBV reduction during dialysis. Because of VO2peak reflects the blood supply capacity, the higher the exercise tolerance of the subject, the more the circulating blood volume to the peripheral tissue was retained, and ΔBV reduction might be prevented. |
