Calculators

  • 1. Solute-Solver LITE single patient calculator (Urea)

    Input pre and post BUN, solve for V, eKt/V, stdKt/V and SAN-stdKt/V. single-treatment calculator.

  • 2. Solute-Solver 2.14 (Urea)

    Input pre and post BUN, solve for V, eKt/V, stdKt/V and SAN-stdKt/V. Program is contained within a single file.

  • 4. Solver-Lite (Urea)

    Good place to start. Only 12 inputs. Uses mg/dL only, no anthropometrics, no hemodiafiltration option nor special modes.

  • 5. What If? (Urea)

    One way to estimate what the Kt/V will be for a patient with a given modeled V and G and different treatment schedules.

  • 6. What is the K0A? (Urea)

    Input clearance values from a dialyzer spec sheet and get the K0A.

  • 7. What is the PBED?

    Calculate equivalent phosphate binder dose.

  • 8. Phosphate Solver 3.02

    Estimate equivalent phosphate binder dose, ingested phosphorus per day, and predialysis serum phosphate. Version 3.0+ updates now include HDF and predialysis hematocrit as an input.

  • 9. Creatinine-Solver 1.23

    Input pre and post serum creatinine, solve for creatinine generation rate plus the usual kinetic variables.

  • 10. What if? (Creatinine) 1.20

    Input creatinine generation rate, estimated volume of distribution, and treatment specs and get estimated pre- and postdialysis serum creatinine, plus plus the usual kinetic variables.

  • 11. What if? (β2M) 1.50

    Input β2M generation rate, estimated volume of distribution, extrarenal clearance and treatment specs and get estimated pre- and postdialysis serum β2M.

LATEST DEVELOPMENTS

2024/04/02 Updated beta version (1.50) of a what-if calculator for beta-2-microglobulin.

2024/01/21 Updated beta version (1.47) of a what-if calculator for beta-2-microglobulin.

2023/12/03 Uploaded a beta version of a what-if calculator for beta-2-microglobulin.

2022/08/27 Updated Phosphate Solver to correct a small convective clearance error (QF sign was reversed in the non-index dialysis treatments for both urea and phosphate). The correction results in a very slight change in clearance.

2022/06/22 Updated Phosphate Solver to include EUDIAL HDF equations, plus a number of housekeeping updates. Predialysis hematocrit is now an input.

2021/09/28 Moved K0A calculator from HDCN to here; Added PBED calculator.

2021/09/25 Added single-patient Kt/V calculator; Fixed maxdate from 2020 to 2025 in Solute Solver; Working on changing grapher from Flash to HTML5.

2019/06/26 Fixed unit conversion bug in phosphate solver when mmol is entered and PREPHOS is entered as 999.

2019/06/04 Fixed unit conversion bugs in creatine solver that were giving erroneous KrCr readings with urine input in micromol format; Fixed semicolon input mode for 996; urea: aligned row output for 996 mode.

2019/01/31 Changed the primary input and reporting variable of Phosphate Solver to estimated (or input) ingested phosphorus instead of absorbable phosphorus.

2018/02/08 Unhid Original stdKt/V calculation with compressed Kru in Solute Solver and Whatif-urea page-by-page output.

2017/10/15 Urea and creatinine solvers updated with new HDF predilution equations. Typo error in Creatinine Solver version 1.18 in computation of dialyzer in-vivo creatinine K0A corrected..
