The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
The re-usable models can be autoclaved up to 50 times, while the modified laryngeal tube (Suction) incorporates an extra lumen for inserting a gastric tube or suction system.

The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm). The increments between gauge sizes are not linear and vary. [2]

[1] This became the forerunner of modern aspirator. [5]
