2-22. INFORMATION REQUIRED ON AN ORDER FOR I.V. FLUIDS
a. Type of fluid to be infused.
b. Volume of the fluid to be infused.
c. Time period over which the fluid is to be infused.
a. I.V. flow rates are regulated in drops per minute (gtts/min).
b. The size of the drop (drop factor) varies from large to small, and depending
on the manufacturer and type of set used, it will require 10, 15, or 20 gtts to equal 1 ml
in standard macrodrip sets, and 60 gtts to equal 1 ml in micro- or minidrip sets. (See
examples in figure 2-6.)
