What color is a 22g IV catheter?

The correct identification of a 22 gauge IV catheter as blue is based on the standard color coding system used in medical practice for intravenous catheters. In this system, specific gauge sizes are associated with designated colors to ensure rapid recognition and appropriate application by healthcare providers.

A 22 gauge catheter, which is commonly used in a variety of situations including fluid administration and medication delivery, is represented by the blue color. This helps distinguish it from other gauges, which have different colors: gray is typically associated with 24 gauge, green with 18 gauge, and yellow with 20 gauge. Knowing these color codes is vital for providers in emergency situations where time and accuracy are crucial, allowing them to quickly select the right catheter size for the clinical need at hand.
