What is an ET tube for?
In its simplest form, the endotracheal tube is a tube constructed of polyvinyl chloride that is placed between the vocal cords through the trachea. It serves to provide oxygen and inhaled gases to the lungs and protects the lungs from contamination, such as gastric contents or blood.
What are the different types of ET tube?
Types of endotracheal tubes include oral or nasal, cuffed or uncuffed, preformed (e.g. RAE (Ring, Adair, and Elwyn) tube), reinforced tubes, and double-lumen endobronchial tubes. For human use, tubes range in size from 2 to 10.5 mm in internal diameter (ID).
What is the difference in an ET and tracheostomy?
An endotracheal tube is an example of an artificial airway. A tracheostomy is another type of artificial airway. The word intubation means to “insert a tube”.
How long can an ET tube stay in?
The 3-week time limit of translaryngeal intubation in critically ill patients was based on the belief that the risk ratio (laryngeal risk vs surgical tracheostomy risk) was excessive if the ETT was left much longer than a month.
What is the size of intubation?
The size of an ETT signifies the inner diameter of its lumen in millimeters. Available sizes range from 2.0 to 12.0 mm in 0.5 mm increments. For oral intubations, a 7.0-7.5 ETT is generally appropriate for an average woman and a 7.5-8.5 ETT for an average man.
What is the difference between cuffed and uncuffed ET tubes?
Cuffed tubes provide a leak-proof connection between the patient’s lung and the bag or ventilator without causing undue pressure to laryngeal or tracheal structures [17]. However, an uncuffed endotracheal tube usually causes air leakage or laryngeal injury.
What are ET tubes made of?
Anatomy of the Standard Endotracheal Tube ETTs are generally made of PVC, although other materials include rubber, silicone, and metal.
What is the difference between ventilator and intubation?
Intubation is the process of inserting a breathing tube through the mouth and into the airway. A ventilator—also known as a respirator or breathing machine—is a medical device that provides oxygen through the breathing tube.

How does one wave valve in endotracheal tube work?
On squeezing the bag to initiate ventilation the one wave valve proximal to the patients outlet opens resulting in release of air , stored in the bag to the patient. On releasing the pressure the bag gets re-inflated with air.
What is the distance indicator on an ET tube?
The distance indicator (marked in centimeters) which facilitates placement of ET tube.4. A cuff- incase of cuff ET tube DISTAL END – has Murphy’s eye (opening in the lateral wall ) which prevents complete blockage of ET tube incase the distal end is impacted with secretion , blood , etc. 5.
