Airway Management: Evaluation, planning, and use of a range of procedures and airway devices for the maintenance or restoration of a patient's ventilation.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.Intubation, Intratracheal: A procedure involving placement of a tube into the trachea through the mouth or nose in order to provide a patient with oxygen and anesthesia.Laryngoscopy: Examination, therapy or surgery of the interior of the larynx performed with a specially designed endoscope.Airway Obstruction: Any hindrance to the passage of air into and out of the lungs.Laryngoscopes: Endoscopes for examining the interior of the larynx.Anesthesiology: A specialty concerned with the study of anesthetics and anesthesia.Fiber Optic Technology: The technology of transmitting light over long distances through strands of glass or other transparent material.ManikinsDisposable Equipment: Apparatus, devices, or supplies intended for one-time or temporary use.Tracheotomy: Surgical incision of the trachea.Cricoid Cartilage: The small thick cartilage that forms the lower and posterior parts of the laryngeal wall.Emergency Medical Services: Services specifically designed, staffed, and equipped for the emergency care of patients.Intubation: Introduction of a tube into a hollow organ to restore or maintain patency if obstructed.

It includes additional use regardless of the original intent of the producer as to disposability or durability. It does not include the repeated use of fluids or solutions.Epiglottis: A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.Laryngopharyngeal Reflux: Back flow of gastric contents to the LARYNGOPHARYNX where it comes in contact with tissues of the upper aerodigestive tract. Laryngopharyngeal reflux is an extraesophageal manifestation of GASTROESOPHAGEAL REFLUX.Laryngeal Diseases: Pathological processes involving any part of the LARYNX which coordinates many functions such as voice production, breathing, swallowing, and coughing.Bronchoscopes: Endoscopes for the visualization of the interior of the bronchi.Equipment Design: Methods of creating machines and devices.Clinical Competence: The capability to perform acceptably those duties directly related to patient care.Glottis: The vocal apparatus of the larynx, situated in the middle section of the larynx.

(From NASA Thesaurus, 1988)Hypoxia, Brain: A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.Video Recording: The storing or preserving of video signals for television to be played back later via a transmitter or receiver.
