Table 2 Position of the endobronchial cuff of RDLT at initial placement and after turning the patients to the lateral decubitus position

From: Comparison of the accuracy of three methods measured the length of the right main stem bronchus by chest computed tomography as a guide to the use of right sided double-lumen tube

  1. The score of endobronchial cuff position (1 = invisible, 2 = visible, not herniated, 3 = slight herniation, ventilation maintained, 4 = herniation, inadequate ventilation); CP Carina-proximal distance, CD Carina to distal distance, CC Carina to carina distance
