Volume/Time – IV mL Rate Questions
Given a certain amount of liquid and a time period, what is the necessary IV flow rate in mL/hr? Measurement used when IV regulated electronically by infusion pump.
Formula:
Example: Infuse 250 mL over the next 120 minutes by infusion pump.
Convert 120 minutes to hours.
- min → hr ( ÷ by 60 )
- 120 min ÷ 60 = 2 hr
Example: Ordered 1000 mL D5W IV to infuse in 10 hours by infusion pump.
