Relating to or administered through the trachea (windpipe); commonly used to describe tubes inserted into the trachea to help with breathing during surgery or critical illness.
From Greek 'endo-' (within) and 'trachea' (windpipe), with the adjective suffix '-al', used in medical and surgical contexts to indicate procedures or equipment placed inside the airway.
If you ever need emergency surgery or are on life support, an endotracheal tube might be placed down your windpipe to keep your airway open and help you breathe—it's one of the most important tools in intensive care.
