What color is an 18g IV catheter?

An 18-gauge intravenous (IV) catheter is color-coded green in accordance with the standardization established by the ISO (International Organization for Standardization) and in use by many healthcare organizations. The color coding of IV catheters allows for quick visual identification of the size of the catheter, which is important in emergency situations where time is of the essence. The green color designates that the catheter is suitable for larger volume infusions and rapid fluid administration, making it particularly useful in trauma cases or when large quantities of fluids need to be delivered quickly. Understanding these color codes can enhance the efficiency and effectiveness of care provided in a clinical setting.
