Equations
Concentration
Concentration (μg/mL) = drug amount (mg) × 1000 ÷ diluent volume (mL)Absolute dose rate
Dose (μg/min) = concentration (μg/mL) × infusion rate (mL/h) ÷ 60Weight-normalised dose
Dose (μg/kg/min) = dose (μg/min) ÷ patient weight (kg)Reverse calculation from absolute dose
Infusion rate (mL/h) = dose (μg/min) × 60 ÷ concentration (μg/mL)Reverse calculation from weight-normalised dose
Dose (μg/min) = target dose (μg/kg/min) × patient weight (kg), then infusion rate (mL/h) = dose (μg/min) × 60 ÷ concentration (μg/mL)References
