What is the difference between micro drip and macro drip?
The drop factor differs (# of gtts/mL). A set that delivers
large drops per mL (10-20 gtt/ml, usually 15) is called macrodrip
set. One uses smaller gtts (60gtt/mL) is called microdrip. Usually
the macrodrip set is used if the IV rate is to infuse >
100ml/hr. Vice versa, Microdrip < 100ml/hr volume. Here is the
drip rate calculation: Volume (mL)/ time (min) x drip factor=
gtt/min ranges 30-100 gtt/min.
