The medical procedure of inserting a flexible plastic tube through the mouth or nose into the trachea to maintain an open airway and enable mechanical ventilation. It's commonly performed during surgery or in critical care situations.
From Latin 'in' (into) and 'tubus' (tube), literally meaning 'to put into a tube.' The suffix '-ation' indicates the process or act of doing something. The procedure was developed in the 19th century for anesthesia administration.
Intubation is literally the difference between life and death in emergency medicine - it can establish an airway in seconds when someone can't breathe on their own. The technique requires incredible skill because you're navigating a tube through the vocal cords into a space barely wider than your thumb, often in life-or-death situations with poor visibility.
