ETT typically stands for "Endotracheal Tube," a medical device used in airway management. It is a flexible plastic tube inserted through the mouth or nose into the trachea to maintain an open airway, deliver oxygen, anesthesia, or medication, and remove blockages or secretions. ETTs are commonly used during surgery, in intensive care units, and in emergency situations to ensure patients can breathe properly. The process of inserting an ETT is known as endotracheal intubation.
