What size is a 24g IV catheter?

The 24g IV catheter is identified by a yellow color, which is a standard coding in intravenous (IV) therapy equipment. This color coding helps healthcare providers quickly identify the size of the catheter, facilitating swift decision-making during patient care. A 24g catheter is one of the smaller gauges, typically used in pediatric patients or individuals with small veins, as it minimizes vessel trauma and discomfort while still allowing for the administration of fluids or medication. The other sizes mentioned, such as 14g, 16g, and 18g, correspond to larger gauges, which are represented by different colors and are more suitable for larger veins or different clinical scenarios requiring faster fluid delivery or blood transfusions.
