Dialysis clearance definition

In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. K – dialyzer clearance of ureat – dialysis timeV – volume of distribution of urea, approximately equal to patient's total body water In the context of hemodialysis, Kt/V is a pseudo-dimensionless … See more K (clearance) multiplied by t (time) is a volume (since mL/min × min = mL, or L/h × h = L), and (K × t) can be thought of as the mL or L of fluid (blood in this case) cleared of urea (or any other solute) during the course of a single … See more Kt/V (in the context of peritoneal dialysis) was developed by Michael J.

See more The URR or Urea reduction ratio is simply the fractional reduction of urea during dialysis. So by definition, URR = 1 − C/C0. So 1−URR = C/C0. So by algebra, substituting into equation (4) above, since ln C/C0 = − ln C0/C, we get: See more Kt/V has been widely adopted because it was correlated with survival. Before Kt/V nephrologists measured the serum urea concentration (specifically the time-averaged … See more • It is complex and tedious to calculate. Many nephrologists have difficulty understanding it. • Urea is not associated with toxicity. See more WebJul 12, 2015 · Definition of "dose" in CRRT is volume of blood "purified." Measure of "dose" in CRRT: clearance rate of a representative marker solute. Practically: Dialysis dose is equivalent to the effluent rate in ml/kg/hour. Effluent rate is the ultrafiltration rate for haemofiltration (CVVH), or the sum of ultrafiltration rate and dialysis rate for CVVHDF
