## What is VISPro?

VISPro is a clinical calculator for the Vasoactive-Inotropic Score (VIS) and Norepinephrine Equivalent (NEE), designed for ICU, cardiac, and critical care teams.

CALCULATE VIS AND NEE IN SECONDS
Enter patient weight and vasoactive drug doses (mcg/kg/min or units/kg/min). VIS and NEE update in real time. Supported drugs include dopamine, dobutamine, epinephrine, milrinone, vasopressin, norepinephrine, and phenylephrine—with formulas aligned to published standards (Gaies et al., NEE literature).

RISK STRATIFICATION AND MORTALITY CONTEXT
See risk level (Low / Moderate / High / Very High) and evidence-based mortality estimates at a glance. Ranges are informed by pooled surgical and ICU data so you can quickly contextualize support level and discuss prognosis.

TRACK TRENDS OVER TIME
Save scores by patient and view VIS and NEE over time. Switch between VIS and NEE on the trend chart, review risk and mortality for each entry, and export or share a concise score report.

BUILT FOR CLINICIANS
• Clean, fast interface—no account required for calculation
• Per-drug VIS and NEE contributions
• Optional NEE calculator with same drug set
• References to key literature (Gaies 2014, VIS meta-analyses, NEE sources)
• Dark mode support
• iPhone and iPad

For clinical use at the bedside or in rounds. Not a substitute for clinical judgment or institutional protocol.
