It consists of a cuffed, double-lumen tube that is inserted through the patient's mouth to secure an airway and enable ventilation.Generally, the distal tube (tube two, clear) enters the esophagus, where the cuff is inflated and ventilation is provided through the proximal tube (tube one, blue) which opens at the level of the larynx.
Ivan Magill later added a cuff (these were glued on by hand to make the famous Blue-line tube copied by many other manufacturers). Maeterlinck GmbH developed the disposable endotracheal tube and produced many design variations, adding the 'Murphy Eye' to their tubes in case of 'accidental' placement of the tube to avoid right bronchial occlusion.
A cuffed endotracheal tube used in tracheal intubation In contrast to supraglottic devices, infraglottic devices create a conduit between the mouth, passing through the glottis, and into the trachea. There are many infraglottic methods available and the chosen technique is reliant on the accessibility of medical equipment, competence of the ...
A tracheostomy tube may be single or dual lumen, and also cuffed or uncuffed. A dual lumen tracheostomy tube consists of an outer cannula or main shaft, an inner cannula, and an obturator. The obturator is used when inserting the tracheostomy tube to guide the placement of the outer cannula and is removed once the outer cannula is in place.
The tracheal tube exchanger is a hollow catheter, 56 to 81 cm (22.0 to 31.9 in) in length, that can be used for removal and replacement of tracheal tubes without the need for laryngoscopy. [22] The Cook Airway Exchange Catheter (CAEC) is another example of this type of catheter; this device has a central lumen (hollow channel) through which ...
In its basic (standard) version, the laryngeal tube is made up of a tube with a larger balloon cuff in the middle (oropharyngeal cuff) and a smaller balloon cuff at the end (oesophageal cuff). The tube is kinked at an angle of 30-45° in the middle; the kink is located in the larger cuff.
A combat medic will typically carry a backpack styled bag known as a "Unit One Pack". Aid bags are available from many different manufacturers, in many different styles. Depending on the unit and their standard operating procedures, the medic may have to follow a strict packing list, or may have the liberty of choosing their kit depending on ...
A tracheostomy tube or endotracheal tube with a 6 or 7 mm internal diameter is then inserted, the cuff is inflated, and the tube is secured. The person performing the procedure might utilize a bougie device, a semi-rigid, straight piece of plastic with a 25-mm tip at a 30-degree angle, to provide rigidity to the tube and assist with guiding its ...
