case_images: Photograph of a "standard" non-channeled blade of the King Vision  videolaryngoscope with a stylet placed in a left 35 Fr double-lumen tube (DLT) to match the contour of the blade.. (
  a) Arrow (1) shows how the proximal DLT curve remains directed to the right side. (
  b) Arrow (2) shows how the distal DLT curve follows the curve of the standard non-channeled blade (approximately 60-70 ). (
  c) Shows the bronchial tip of the DLT adapted to the tip of the standard non-channeled blade.
