IV flow rate calculations determine the flow rate of solution administered over a given time. This is normally expressed as mL/Hr or mL/min. However, you should also know how to determine how much volume would be administered using time and rate.
The flow-rate calculation below is determining how long it would take to deliver a volume at a particular rate.
A physician orders a drug to be infused at:10mcg/kg/min. The patient weighs 70kg. The total dose the patient is to receive is 21mg. How long must the IV continue for the patient to receive this dose?
