IVF (mL/h)
mL/h=
Total infusion volume/ Total infusion time
Ex.
mL/h= 3,000mL (total infusion volume)
24 h (total infusion time)
= 125 mL/h
Micro= 60
Macro= 15 (10,15,20)
Drops per minute
Total infusion volume X drop factor/
Total time of infusion in minutes
Drops per minute=
1,000mL x 20 gtts/mL
(8h X 60mins)
=41 drops/min
Duration or Total time of infusion in Hours
Total infusion volume X Drop factor
Drops per minute X 60 minutes/hour
