Definitions related to laryngeal masks:
-
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(laryngeal mask airway) A supraglottic airway device that is composed of an airway tube that connects to an inflatable elliptical mask on the distal end which is inserted through the patient's mouth, down the trachea, and inflated to form an airtight seal on top the glottis.NCI ThesaurusU.S. National Cancer Institute, 2021
