Figure 1From: Assessment of Truflex™ articulating stylet versus conventional rigid Portex™ stylet as an intubation guide with the D-blade of C-Mac™ videolaryngoscope during elective tracheal intubation: study protocol for a randomized controlled trial Enhanced angulation of the D-blade of the C-Mac™ videolaryngoscope. (a) Shown is the sharper blade angulation of the D-blade of the C-Mac™ videolaryngoscope versus the conventional Macintosh laryngoscope blade. (b) The natural curvature of the traditional endotracheal tube does not match the enhanced angulation of the D-blade of the C-Mac™ videolaryngoscope.Back to article page
