Step-by-step explanation:
The common gauge used with winged infusion sets is typically between 18 and 22. The gauge refers to the diameter of the needle, with a lower gauge number indicating a larger needle size. The winged infusion set, also known as a butterfly needle, is commonly used for venipuncture procedures where a smaller needle gauge is required for delicate veins or when a shorter puncture is desired. For example, an 18 gauge needle is larger in diameter than a 22 gauge needle.
