Understanding IV Cannula Color Code

Introduction

An intravenous (IV) cannula is a flexible tube inserted into a patient’s vein to administer fluids, medication, or to collect blood samples. IV cannulas come in different sizes and styles, each serving specific purposes. To quickly identify their characteristics, manufacturers assign different color codes to IV cannulas.

Understanding the IV cannula color code is crucial for healthcare professionals. This guide provides an overview of the most commonly used color codes and their corresponding sizes and purposes.

Green:

The green-colored IV cannula typically indicates a standard-size cannula with a gauge of 18G or 20G. They are commonly used for routine procedures, such as administering fluids or medications.

Blue:

Blue-colored IV cannulas usually have a smaller gauge, ranging from 22G to 24G. These cannulas are suitable for patients with fragile or small veins, such as children or elderly individuals.

Pink:

Pink-colored IV cannulas are designed for patients requiring blood transfusions. They typically have a larger gauge, often 16G, and are specially designed for efficient blood flow.

Yellow:

Yellow-colored IV cannulas are often longer in length and have a larger gauge, around 14G or 16G. They are commonly used for rapid fluid administration or in emergency situations.

Orange:

Orange-colored IV cannulas are typically used for pediatric patients. They have a smaller gauge, often 24G or 26G, and are designed to minimize discomfort during insertion.

Conclusion

Understanding the color code associated with IV cannulas is essential for healthcare professionals to ensure proper selection and usage. The color-coded system helps medical teams quickly identify the size and purpose of the cannulas, promoting efficient and safe patient care.
