Unlike the Birmingham gauge, where larger gauge numbers indicate smaller diameters, an increasing French size corresponds to a larger outer diameter. The French scale measures …

The key thing to remember is that the French scale measures the outside diameter, not the inside (or lumen) size. This is important because the thickness of the catheter wall can vary …

When referring to sheaths, the French size refers to the inner diameter, thereby telling you the largest catheter that will fit through the sheath. The outer diameter of a sheath is ~2 Fr larger, …

The French size of a catheter is determined by a simple multiplication of 3 (diameters in millimeters multiplied by 3 = the French size). For example, if a catheter has a diameter of 4.7 …

1 day ago · Polyurethane tubes, with thinner walls, allow a larger internal lumen at the same outer diameter, enhancing flow efficiency. Silicone tubes offer superior biocompatibility and reduced …

Aug 19, 2024 · In simpler terms, a catheter with a French size of 14 has a diameter of 4.7 mm, while a size 16 has a diameter of 5.3 mm. The larger the French size, the wider the catheter.
