  1. I. Distance between the bronchial lumen tip (patient end) and the tip of the pilot balloon/inflation valve (the longest length)
  2. II. Distance between the bronchial lumen tip (patient end) and bronchoscope port
  3. III. Distance between the bronchial lumen tip (patient end) and slip joint (however, we did not measure the distance on Portex and Daiken-medical because they do not have structurally slip joint)
  4. IV. Distance between the bronchial lumen tip (patient end) and the Y-shaped connector
