WebNov 12, 2024 · The renal plasma flow (RPF) is the amount of plasma that enters the kidneys every minute. It can be calculated if we know the RBF and the haematocrit, like this: Renal plasma flow = RBF x (1 – haematocrit) The RPF is normally 600 – 800 mL/min. Clearance of PAH: See previous topic.
