Endotracheal is a medical term used to describe an invasive procedure where a tube is inserted through the mouth or nose and into the windpipe to allow for artificial ventilation. Some common synonyms for the term endotracheal include intubation, endotracheal intubation, endotracheal tube insertion, and airway intubation. These synonyms are often used interchangeably in medical contexts and refer to the same medical procedure. The procedure is typically performed in emergency situations or during surgeries to maintain and control the flow of air to the lungs. Regardless of the term used, endotracheal procedures are critical for the successful management of respiratory failure.
