Dimensional Variations of Left-Sided Double-Lumen Endobronchial Tubes

Table 6

Measured angles of the investigated left-sided double-lumen endobronchial tubes (DLTs) between a virtual longitudinal line through the middle of the tracheal tube shaft and bronchial tube (see also Figure 1).

DLT sizes are in French (= 1/3 mm). Data is displayed as median (minimum-maximum) and dimension is degrees (°).
