An endotracheal intubation is a medical procedure in which a tube is placed into the windpipe (trachea). This is done to open the airway to give you oxygen, medication, or anesthesia.
After an intubation, you will likely be placed on a machine called a respirator that will breath for you while the tube is in place.
Endotracheal intubation may also be done to remove blockages or to view the interior walls.
