In some special treatments, it is important to adjust the speed of drug infusion in extracorporeal veins, such as dopamine, nitroglycerin and so on. But sometimes it takes time to calculate its concentration.
Drug infusion rate calculation
(1) Intravenous infusion rate and time reference data
|Liquid volume(ml)||Dropping speed(gtt/min)||time（h）|
\(concentration (mg/ml) × 1000 (mcg) ÷ 60 (min) ÷ weight (kg) = constant \)
Then use this constant to determine the infusion rate and dose
\ (speed (ml / h) = doctor's dose ÷ constant \)
\ (dose (mcg/kg/min) = infusion speed × constant \)
The purpose of this tool is only to reduce the cumbersome human calculations and improve the efficiency of medical staff.
