The laryngeal tube is also recommended for medical personnel not experienced in tracheal intubation, and as a rescue device when intubation has failed in adults. [16] According to the manufacturer the use of Laryngeal tubes is contraindicated in people with an intact gag reflex , known oesophageal disease , and people who have ingested caustic ...
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.
Retroglottic airway devices (RGAs) pass behind the glottis and into the esophagus to create a seal allowing oxygen to be delivered directly to the trachea. [3] [5] The RGAs are designed as laryngeal tubes. [3] Examples of RGAs include the Combitube and the King LT. Studies comparing the effectiveness between the RGAs are lacking.
A device called the Positube, which allows for esophageal intubation detection, can be used on tube number two to rule out the intubation of the Combitube in the trachea. The Positube checks for air flow resistance on tube number two and is very helpful in checking proper Combitube placement when intubation is performed in noisy environments.
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent (open and unobstructed) airway. Tracheal tubes are frequently used for airway management in the settings of general anesthesia, critical care, mechanical ventilation, and emergency medicine. Many different types of ...
in unconscious patient (single cuff is sufficient); used in permanent tracheostomy (with two cuffs); has a balloon (cuff) that is inflated to occlude the airway around the tube to prevent aspiration of fluids into the lungs •Jackson's: metal double tube and a pilot Retractor's (single or double hook) to retract tissues Tracheal hooks (blunt ...
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 breathing circuit is the ducting through which the breathing gases flow from the machine to the patient and back, and includes components for mixing, adjusting, and monitoring the composition of the breathing gas, and for removing carbon dioxide. A modern anaesthetic machine includes at minimum the following components: [2]
