Table 4:
Summary of metabolic parameters derived from K-MOTIVE and db-K-MOTIVE from 10 subjects. Parameters from right renal vessels were unavailable in three of the subjects. In such instances, the left renal parameters were doubled for subsequent bilateral calculations. Measurements are expressed as mean ± S.D. Abbreviations: SvO2 = venous oxygen saturation; AVDO2 = arteriovenous difference in oxygen saturation; blood flow rate = BFR; and rMRO2 = renal metabolic rate of oxygen.
