Dialysis clearance definition
Web'Diffusive Clearance' published in 'Encyclopedia of Intensive Care Medicine' In the above equation, the overall resistance to diffusive mass transfer of a particular solute (R O) by a dialyzer has three components: blood compartment resistance (R B), resistance due to the membrane itself (R M), and dialysate compartment resistance (R D).In turn, R O is the … WebSo clearance has the units of a flow rate. Looked at another way, clearance is the relationship between the traffic of i through the body (Ui x Vu) and its plasma concentration, Pi . Physicians all use clearance. …
