The PD Kt/V Calculator is an indispensable tool for healthcare professionals and patients on peritoneal dialysis. This online calculator helps you determine the adequacy of PD treatment by calculating weekly Kt/V, creatinine clearance (Ccr), and effective Kt/V (eKt/V). Accurate assessment is crucial for optimizing dialysis prescriptions and improving patient outcomes. Quickly evaluate both dialysate and renal contributions to total clearance.
Formula:
The PD Kt/V Calculator uses the following standard formulas to determine peritoneal dialysis adequacy:
Weekly Dialysate Kt/V (PD Kt/VD) = (D_Urea × D_Vol × 7) / (P_Urea × V)
Weekly Renal Kt/V (PD Kt/VR) = (U_Urea × U_Vol × 7) / (P_Urea × V)
Effective Weekly Kt/V (eKt/V) = PD Kt/VD + PD Kt/VR
Weekly Dialysate Creatinine Clearance (CcrD) = (D_Crea × D_Vol × 7) / P_Crea
Weekly Renal Creatinine Clearance (CcrR) = (U_Crea × U_Vol × 7) / P_Crea
Effective Weekly Creatinine Clearance (eCcr) = CcrD + CcrR
Where:
- D_Urea = Dialysate Urea Nitrogen concentration (mg/dL)
- D_Vol = 24-hour Dialysate Drain Volume (L)
- P_Urea = Plasma Urea Nitrogen concentration (mg/dL)
- V = Total Body Water Volume (L)
- D_Crea = Dialysate Creatinine concentration (mg/dL)
- P_Crea = Plasma Creatinine concentration (mg/dL)
- U_Urea = Urine Urea Nitrogen concentration (mg/dL)
- U_Vol = 24-hour Urine Volume (L)
- U_Crea = Urine Creatinine concentration (mg/dL)
