Standard Kt/V (weekly dialysis dose)

Standard (weekly) Kt/V via the Leypoldt / Daugirdas equilibrated conversion from single-pool Kt/V, session length, and weekly frequency, against the >= 2.1/week adequacy target.

Example

Single-pool Kt/V
1.4
Session length
240 minutes
Sessions per week
3

Result: Standard Kt/V 2.18/week (eKt/V 1.22): meets the >= 2.1/week adequacy target.

The tool opens with these values already filled in. Replace them with your own.

What the result means

Target
KDOQI 2015 weekly adequacy target is at least 2.1/week; lets thrice-weekly, short-daily, and nocturnal schedules be compared on one axis.

What you enter

  • Single-pool Kt/V
  • Session length
  • Sessions per week
How this is calculated
Formula
eKt/V = spKt/V x time / (time + 35) (Tattersall, minutes); stdKt/V = (10080 x (1 - e^-eKtV) / time) / ((1 - e^-eKtV)/eKtV + 10080/(sessions x time) - 1).
