Abstract
An endotracheal tube assembly with a plurality of curved portions is provided. A first curved portion in the endotracheal tube assembly is located adjacent to an insertion end thereof with a curvature that matches the curvature of a video laryngoscope (e.g., Glidescope®). A second curved portion in the endotracheal tube assembly is located in a central portion of the endotracheal tube assembly. The curvature of the first curved portion is greater than the curvature of the second curved portion. The first curved portion is bent at an angle of between about 120° and about 150° with respect to a straight portion of the endotracheal tube assembly. The second curved portion is bent at an angle of between about 30° and about 60° with respect to the straight portion of the endotracheal tube assembly.
