Frequently asked questions
Multiply volume by drop factor and divide by time in minutes. 1000 ml over 480 minutes with a 20 gtts/ml set is about 42 drops per minute.
It is how many drops make a millilitre for a particular giving set, printed on the packaging — often 10, 15, 20 or 60 gtts/ml.
A microdrip set delivers 60 drops per millilitre, used for precise, slow infusions such as in paediatrics.
