Vasoactive-Inotropic Score (VIS) Calculator

  • Dopamine (µg/kg/min)
  • Dobutamine (µg/kg/min)
  • Epinephrine (µg/kg/min)
  • Norepinephrine (µg/kg/min)
  • Vasopressin (U/kg/min)
  • Milrinone (µg/kg/min)
  • Vasoactive-Inotropic Score (VIS): Explanation and Clinical Context
    The Vasoactive-Inotropic Score (VIS) quantifies the amount of cardiovascular support a patient receives through vasoactive and inotropic medications. It was originally developed to assess post-operative outcomes in pediatric cardiac surgery, correlating higher scores with increased morbidity and mortality.
    The VIS is calculated as: VIS = dopamine (µg/kg/min) + dobutamine (µg/kg/min) + 100 × epinephrine (µg/kg/min) + 100 × norepinephrine (µg/kg/min) + 10 × milrinone (µg/kg/min) + 10 × vasopressin (U/kg/min).
    This score provides a standardized method to quantify the intensity of cardiovascular pharmacologic support and helps clinicians predict hemodynamic instability and adverse outcomes.
