Flow rate calculation: When calculating the flow rate of IV solutions, that the number of drops required to deliver 1 ml varies with the type of istration set. istration sets are of two types:  Macro drip set (delivers 10-20 drops/ml )  Micro drip set (60 drops/ml). Flow rate =

Volume of infusion in ml Time of infusion in minutes

x Drip factor (in drops/ml)
