A–C = distance from bifurcation (beginning of DLT shaft, A) to the proximal edge of the tracheal cuff (C); C-D = length of the tracheal cuff; D-E = distance between distal edge of the tracheal cuff (D) to the proximal edge of the bronchial Cuffs (E); E-F = length of the bronchial cuff; F-G = distance between the distal edge of the bronchial Cuffs (F) to the tip of the tube (G); A–G = tube length from bifurcation (A) to the tip of the tube (G) (see also Figure 1). DLT sizes are in French (= 1/3 mm). Data are displayed as median (minimum–maximum) given as millimeter (mm). The greatest length of a respective DLT size is shaded in gray (100%), and the smallest diameter is marked with an asterisk () (proportion of largest OD).
