Infusion Dose Calculator Calculate the drug dose rate (per minute and per kg per minute) for any infusion. You can also set an infusion drug dose rate and it will calculate the required infusion rate in mL/min instead. Independent inputs Variable Value Units Patient weight kg Drug amount mg Diluent volume mL Concentration: — mg/mL […]
