CSAMIDDLE = cross-sectional area in the middle (B) between the beginning of the DLT shaft (A) and the proximal edge of the tracheal cuff (C); CSAPTC = cross-sectional area at the proximal edge of the tracheal cuff (C); CSADTC = cross-sectional area at the distal edge of the tracheal cuff (D); CSAPBC = cross-sectional area at the proximal edge of the bronchial cuff (E); CSADBC = cross-sectional area at the distal edge of the bronchial cuff (F) (see also Figure 1). DLT sizes are in French (= 1/3 mm). Data are displayed as median (minimum-maximum) given as millimeter [2]. The largest CSA of a respective DLT size is shaded in gray (100%), and the smallest diameter marked is with an asterisk () (proportion of largest OD).
