Daugirdas 1993 second-generation single-pool variable-volume Kt/V
Daugirdas 1993 second-generation single-pool variable-volume Kt/V. Kt/V = -ln(R - 0.008 * t) + (4 - 3.5 * R) * UF / W, with R = post_bun_mg_dl / pre_bun_mg_dl. Numeric Kt/V to 2 decimals. Not a dialysis prescription, not equilibrated eKt/V, not stdKt/V, and not a urea-reduction-ratio tool. magent does not assign KDOQI or other adequacy targets.
