Table 1. Definitions of the parameters used.
Baseline microvascular resistance (BMR) | Paorta / bAPV |
Hyperemic microvascular resistance (HMR) | Paorta / hAPV |
Renal flow velocity reserve (RFVR) | hAPV / bAPV |
Renal resistance reserve (RRR) | HMR / BMR |
APV indicates average peak flow velocity; Paorta, aortic pressure; b, baseline; h, hyperemia
