CMAC blade comparison

Two Storz CMAC blades are shown to illustrate the Macintosh-style (size 3, on the left) and the acute angled D-blade (on the right). The D-blade may be more versatile, especially for anatomically difficult airways. Direct laryngoscopy may be possible with the Macintosh-style blade, but is usually not feasible with the D-blade. For further details, refer to UpToDate content on video laryngoscopy.
