Which sheath size is represented by the color green?

Explanation:
Color coding of vascular sheaths is a quick-reference system used in the cath lab to identify the French size of a sheath without needing to read small print. This helps the team pick compatible devices and avoid using a sheath that’s too large or too small for the planned catheters and interventions. In the commonly taught mapping, green corresponds to a 6 French sheath. This size sits between smaller 4F/5F options and larger 7F options, and the outer diameter is about 2.0 mm. Remember that some brands may differ in their color schemes, so always check the labeling on the sheath if there’s any doubt.
