  1. Pearson analysis showed that there was no statistical correlation between blood gas PaCO2 and ventilation mode, ASA classification, lesion location, stenosis degree, body mass index and procedure duration
  2. COT conventional oxygen therapy; NFJV normal frequency jet ventilation; HFJV high frequency jet ventilation
  3. Lesions location: 1) the upper and middle part of the main airway, 2) the middle and lower part of the main airway, 3) the left or right main bronchial and 4) in the distal bronchial. Degree of stenosis: 1 for 0–59%, 2 for 60–89%, and 3 for above 90%
