Question: 1 / 400

What is the gauge size of an orange IV catheter?

12g

14g

The gauge size of an orange IV catheter is 14g. This size is commonly used for trauma patients, those with significant blood loss, or in situations where rapid fluid or medication administration is necessary. The larger the gauge number, the smaller the diameter of the catheter, so a 14-gauge catheter has a larger lumen than those of 16g or 18g, allowing for quicker fluid delivery.

In emergencies, the ability to administer fluids or blood products efficiently can be critical for patient outcomes, particularly in cases of shock or significant dehydration. Recognizing the color coding associated with catheter sizes helps healthcare providers quickly identify the appropriate gauge for the situation. In this case, the orange catheter is specifically identified with the 14-gauge size, making it an effective choice for high-demand usage in emergency medical services.
