The removal of an endotracheal tube from a patient's airway, typically performed when the patient can breathe adequately on their own. This procedure marks the transition from mechanical ventilation back to spontaneous breathing.
From Latin 'ex-' meaning 'out of' + 'tubus' meaning 'tube' + '-ation.' The term emerged in the 20th century with the development of modern anesthesia and mechanical ventilation techniques, describing the reversal of intubation.
