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.
Extubation is often more dangerous than intubation itself! About 10% of extubations fail, requiring emergency re-intubation, which is why it's sometimes called 'the moment of truth' in intensive care - it reveals whether a patient has truly recovered enough to breathe independently.
