Step 1: Convert inputs to common units.
Step 2: Solve equation.
Flow Rate = V / T
Flow Rate = 1000 / 8 = 125 mL/hr
Result = 125 mL/hr
Electronic infusion pumps deliver IV fluids at a precise rate measured in milliliters per hour (mL/hr). Unlike gravity drip IVs, electronic pumps do not require a drop factor since they control the flow mechanically.
This calculator can solve for any one of the three variables (flow rate, time, or volume) when the other two are known.
Calculate Electronic IV Rate ↑Order: Infuse 1,000 mL of NS over 8 hours.
Flow Rate = 1000 / 8 = 125 mL/hr
An infusion pump uses standard IV bags and tubing, delivering larger volumes at rates typically ranging from 1 to 999 mL/hr. A syringe pump holds a prefilled syringe and delivers very small, precise volumes, ideal for concentrated medications or neonatal care.
Electronic infusion pumps control flow rate mechanically, not by gravity. The drop factor of the IV tubing is irrelevant when using a pump because the pump precisely meters the fluid electronically. Drop factor only matters for manually regulated (gravity) IVs.
