 Diagram of an endotracheal tube (10) that has been inserted into the airway of a patient. An endotracheal tube (ETT) is used in anaesthesia, intensive care and emergency medicine for airway management and mechanical ventilation. It is regarded as the most reliable available method for protecting a patient's airway. Image File history File links No higher resolution available. ...

Inventor David S Sheridan was the inventor of the modern "disposable" plastic endotracheal tube now used routinely in surgery. Previous to his invention, red rubber tubes were used, then sterilyzed, and re-used which often lead to the spread of disease and also a high risk of infection. Mr Sheridan is credited with saving thousands of lives.
He also held more than 50 medical instrument patents. Mr Sheridan died April 29 2004 in Argyle, New York at the age of 95.
Procedure It is inserted into the trachea, generally via the mouth, but sometimes through the nares of the nose (e.g. in extensive mouth surgery) or even through a tracheostomy. The process of inserting an ETT is called intubation. Look up trachea in Wiktionary, the free dictionary. ...
Tracheotomy is a surgical procedure used to cut a hole in the trachea through which a small tube is inserted. ...
Intubation being practiced on a dummy (conventional technique using a laryngoscope). ...
Intubation usually requires general anesthesia and muscle relaxation but can be achieved in the awake patient with local anaesthesia or in an emergency without any anaesthesia, although this is extremely uncomfortable and generally avoided in other circumstances. This article or section may be confusing for some readers, and should be edited to be clearer. ...
Local anesthesia is any technique to render part of the body insensitive to pain without affecting consciousness. ...
It is usually performed by visualising the larynx by means of a hand-held laryngoscope but can also be performed "blind". A stylet is normally used in an intubation which is a bendable piece of metal inserted into the ETT as to make the tube more stiff for easier insertion, this is then removed after the intubation and a ventilator or bag valve mask is attached to the ETT. The goal is to position the end of the ETT 2 centimeters above the bifurcation of the lungs or the carina. If inserted too far into the trachea it mainly goes into the right mainstem of the bronchial tree. Laryngoscope in use intubating a dummy A laryngoscope is a medical instrument that is used to obtain a view of the glottis by direct laryngoscopy. ...
Types There are many types of Endotracheal tubes (ETT). Endotracheal tubes range in size from 3-10.5 mm in internal diameter (ID) - different sizes are chosen based on the patient's body size with the smaller sizes being used for pediatric and neonatal patients. Tubes larger than 6 mm ID tend to have an inflatable cuff. Special double-lumen endotracheal tubes have been developed for lung and other intra-thoracic surgery. These tubes allow one-lung ventilation while the other lung can be collapsed to make surgery easier. Another type of endotracheal tube has a second lumen which the opening is situated right above the inflatable cuff, this is a suction port. This allows a suction system to be connected to the ETT to allow for suctioning of secretions which sit above the cuff. This has been proven to decrease the amount of bacteria which could possible grow in the secretions causing a longer stay in the hospital. A millimetre (American spelling: millimeter), symbol mm is an SI unit of length that is equal to one thousandth of a metre. ...
