VVR Calculator

Vasoactive Ventilation Renal Score (VVR)

VVR = VIS + VI + (ΔCr × 10)

The Vasoactive Inotrope Score is the sum of the following — it is automatically calculated for you

Vasoactive Inotrope Score (VIS)

Input the current infusion dosages to determine the VIS

(mcg/kg/min)
(mcg/kg/min)
(mcg/kg/min × 100) =
(mcg/kg/min × 10) =
(units/kg/min × 10,000) =
(mcg/kg/min × 100) =
Ventilation Index (VI)

Complete the following fields to determine the Ventilation Index

Ventilation Index (VI) = ( RR × (PIP-PEEP) × PaCO2 ) / 1000 — it is automatically calculated for you

Ventilation Index (VI)

Complete the following fields to determine ΔCr

ΔCr = (Postoperative Creatinine - Preoperative Creatinine) × 10 — it is automatically calculated for you

For postoperative creatinine, use the most recent measurement at time of VVR calculation
