In most general hospital settings, the pink-colored 20-gauge IV cannula is often considered the most commonly used IV cannula size, though the blue 22-gauge is also a frequent choice, depending on the patient's needs and vein condition. The selection is a careful balance between required flow rate and minimizing patient discomfort.

In medicine, needle gauge size has an inverse relationship with its diameter—meaning a higher gauge number indicates a smaller, thinner needle. Understanding this principle is the first step toward answering the question: what do you use a 20 gauge for, and when is this size most appropriate for patient care?

According to established medical guidelines, a standard 20-gauge IV catheter is typically rated for a maximum flow rate of approximately 60 milliliters per minute. This practical guide explores exactly how fast you can run fluids through a 20g IV, covering the key variables that affect this speed and ensuring optimal patient care.

Did you know that IV catheters are color-coded to prevent medical errors and simplify patient care? Learning what color is a 20-gauge IV is a crucial piece of this standardized system used by healthcare professionals worldwide.
