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.

A dose-sparing syringe and needle being used to draw up a COVID-19 vaccine. A dose-sparing syringe is one which minimises the amount of liquid remaining in the barrel after the plunger has been depressed.

In many hospitals and other health facilities, suction is typically provided by suction regulators, connected to a central medical vacuum supply by way of a pipeline system. The plastic, rigid Yankauer suction tip is one type of tip that may be attached to a suction device. Another is the plastic, nonrigid French or whistle tip catheter.
Its size mainly ranges from 14 to 26 [2] gauge. Different-sized cannula have different colours as coded. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula ( extubation ), [ 3 ] especially of a tracheostomy [ 4 ] cannula, once a physician determines it is no longer needed for breathing.
