Question

Given the following data about a patient, show the steps to determine the Renal Blood Flow. The answer is 690mL/min but I cannot for the life of me figure out how this is calculated. Please show all the work in your answer.

Explanation / Answer

Calculation of renal blood flow= renal blood flow=renal plasma flow/1-hemotocrit, here renal blood flow is 690ml/min, and hemotocrit is a 0.42, then 690(rbf)=rpf(not know)/1-hemotocrit is 0.42, so 690*1-0.42=282.9(in other words 282.9x100/41=690).
