Insertion of a folded laryngeal mask airway around a palatal torus
1ProDental, Columbia, MO, USA.
Abstract:
The laryngeal mask airway (LMA) is an airway management device that is used to establish and maintain a patent airway for the patient. A palatal torus is a common benign bony exostosis, usually located in the midline of the palate, beneath the palatal mucosa. It should be recognized by the CRNA during the preoperative anesthetic assessment. A palatal torus can hinder insertion of the LMA when using the standard LMA insertion technique. Therefore, modification must be made to the operator's insertion technique with a folded LMA around a palatal torus.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
