Nasopharyngeal passage of an endotracheal tube can be facilitated by a flexible Wendl tube (nasopharyngeal airway) covering and guiding the rigid tube tip. This technique is helpful in reducing the incidence and severity of nosebleeds and in minimizing contamination of the tip of the endotracheal tube with blood and mucus.
