About This Calculator

Glucose infusion rate is a measure of how quickly the patient receives carbohydrates. Typically, this number should be less than 4 mg/kg/min in order to prevent hyperglycemia and steatosis.1

This calculator uses the following equation to determine a glucose infusion rate:

GIR = (Concentration, g/100 mL) x (Infusion rate, mL/hr) x (1000 mg/g)
(Weight, kg) x (60 min/hr)
