Figure
Example of a size 2.5 (left) and 3.0 (right) Shiley™ uncuffed tracheal tube (TT) (Covidien™, Mansfield, MA, USA). Each TT has insertion depth marks printed (in cm) along the length of the TT. In addition, each TT has two glottic depth marks printed on the distal end. The package inserts indicate the location (in mm) of the glottic depth marks A and B from the tip of the TT
