A laryngeal mask is composed of an airway tube that connects to an elliptical mask with a cuff which is inserted through the patient's mouth, down the windpipe, and once deployed forms an airtight seal on top the glottis (unlike tracheal tubes which pass through the glottis) allowing a secure airway to be managed by a health care provider.
The laryngeal mask airway (LMA) is a tube with an inflatable cuff. A laryngeal mask airway can be positioned in the lower oropharynx to prevent airway obstruction by soft tissues and to create a safe channel for ventilation. The laryngeal mask airway is the standard rescue ventilation when endotracheal intubation cannot be accomplished.
This is suggested to be due, in part, to decreased no-flow-time in which vital organs, including the heart are not adequately perfused. Establishment of an advanced airway ( endotracheal tube , laryngeal mask airway ) allows for asynchronous ventilation, reducing the no-flow ratio, as compared to the basic airway ( bag-valve mask ) for which ...
Laryngeal mask airway [ edit on Wikidata ] The laryngeal tube (also known as the King LT ) [ 1 ] is an airway management device designed as an alternative to other airway management techniques such as mask ventilation , laryngeal mask airway , and tracheal intubation .
The upper respiratory tract can refer to the parts of the respiratory system lying above the vocal folds, or above the cricoid cartilage. [4] [5] The larynx is sometimes included in both the upper and lower airways. [6] The larynx is also called the voice box and has the associated cartilage that produces sound.
They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system. Agents of significant contemporary clinical interest include volatile anesthetic agents such as isoflurane , sevoflurane and desflurane , as well as certain anesthetic gases such as nitrous ...
Airway obstruction is commonly caused by the tongue, the airways itself, foreign bodies or materials from the body itself, such as blood or vomit. [ 2 ] Contrary to advanced airway management , basic airway management technique do not rely on the use of invasive medical equipment and can be performed with less training.
Laryngeal mask airways can even be used to deliver general anesthesia or intubate a patient through the device. These are followed by infraglottic techniques, such as tracheal intubation and finally surgical techniques. Advanced airway management is a key component in cardiopulmonary resuscitation, anesthesia, emergency medicine, and intensive ...
