Also know, what size is a green cannula?
Green-colored cannulae also are considered to be a standard size. Measuring as an 18 gauge, with a fluid flow rate of 90 milliliters per minute, this cannula size is used for routine blood transfusions, transfusing large volumes of fluid, intravenous feeding of patients and the harvesting and separation of stem cells.
