French Catheter Size Chart

French Catheter Size Chart - 1 fr equals 0.33 millimeters. The catheter's diameter in millimeters is determined by dividing the fr size by 3: Enter a value in a cell and click the calculate button in the same row to determine approximate equivalence in the other unit. The french scale measures and is proportional to the outer diameter of a catheter, with 1 french (fr) defined as millimeter, making the relationship: Internal catheters usually have their outside diameters measured in french sizes. Unlike inches or millimeters, which might seem more familiar, the french scale has its own unique system:

Ensure catheter size does not exceed 45% of the diameter of the vein's internal lumen Enter a value in a cell and click the calculate button in the same row to determine approximate equivalence in the other unit. See the below chart for the most common. D(mm)=fr/3 or fr = d(mm) x 3 Learn what they mean, how to choose the right size, and why it matters for comfort and effective drainage.
