The Endotracheal Tube is a temporary breathing device in which a tube is placed into the windpipe (trachea) through the mouth or nose. Endotracheal intubation is often used during surgery and in a variety of emergencies.
Many different types of ETTs are available, suited for different specialized situations. They have several common characteristic design features. The following article will give you a detailed explanation. Please scroll down and start reading.

The endotracheal tube (ETT) is a temporary breathing device inserted into the patient's trachea. It is a flexible hollow plastic tube, usually made of polyvinyl chloride (PVC). It was passed into the trachea through the mouth (oral) or nose (nasal) to establish a patent airway and ensure adequate gaseous exchange or ventilation. Available in a variety of sizes and styles to suit patient needs. It is commonly called an ETT or ET tube.
Many different types of ETTs are available, suited for different specialized situations. The vast majority of ETTs have several characteristic design features that are listed below.
Endotracheal tubes typically have a left-facing-bevel at the tip. While the endotracheal tube approaches the vocal cords, the left-facing bevel provides an optimal view. The bevel face is left rather than right so that the ETT tip can more easily cross the vocal cords.
The Murphy's eye is a hole on the side of the tip of the endotracheal tubes that functions as a vent and prevents the complete obstruction of the patient's airway when the primary distal opening of an ETT becomes obstructed. Without Murphy's eye, the endotracheal tube would have been completely obstructed.
The cuff of the endotracheal tube (ETT) is designed to provide a seal within the airway, allowing airflow through the ETT but preventing the passage of air or fluids around the ETT. Paediatrics tubes are usually uncuffed because their tracheal is easily damaged by pressure.
There are generally two types of endotracheal tube cuffs in use, namely high volume - low pressure cuffs and low volume - high pressure cuffs.
The proximal tip of the Endotracheal tube (ETT) has a standard 15mm connector. 15mm is the outside diameter of the connector. Endotracheal tube connectors connect the endotracheal tube to the breathing system.
Most ET tubes include a radio-opaque line that extends to the tip for x-ray visualization.
Endotracheal tubes have incremental markings from the tip to characterize the distance from the tip to the level of the incisor as insertion depth.
The endotracheal tube is measured from the distal end of the tube and typically marked in 2 cm increments.
Other types of Endotracheal Tubes include:
Reinforced Endotracheal Tube
Pre-formed Endotracheal Tube
ETT With Evacuation Lumen
