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.
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.
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 ...
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 ...
Blind insertion airway device, curved tube for ventiliation; Laryngeal mask airway, a supraglottic airway device used in anesthesia and in emergency medicine for airway management; Medical ventilator, a machine which may be connected to a mask, laryngeal mask airway or tracheal tube to mechanically move breatheable air into and out of the lungs
Laryngeal mask airway (LMA). Example of a supraglottic device. Management of the airway in the emergency department is optimal given the presence of trained personnel from multiple specialties, as well as access to "difficult airway equipment" (videolaryngoscopy, eschmann tracheal tube introducer, fiberoptic bronchoscopy, surgical methods, etc ...
Medical equipment commonly used includes oropharyngeal airway, nasopharyngeal airway, bag valve mask, and pocket mask. [2] Airway management is a primary consideration in cardiopulmonary resuscitation, anaesthesia, emergency medicine, intensive care medicine and first aid.
