extubation
Pronunciation: eks-too-BAY-shun
The planned removal of an endotracheal tube from a patient who has been mechanically ventilated.
Full Definition
Extubation is the process of removing an artificial airway (endotracheal or tracheostomy tube) when mechanical ventilatory support is no longer needed or when transitioning to less invasive respiratory support. Successful extubation requires careful assessment of respiratory function, neurological status, and ability to protect the airway. Pre-extubation protocols typically include spontaneous breathing trials, cuff-leak tests, and evaluation of secretion management. Failed extubation requiring reintubation within 24-48 hours is associated with increased morbidity and mortality. Post-extubation monitoring for respiratory distress or airway obstruction is critical.
Usage
Usage note: Verb form is 'extubate'; distinguish from 'decannulation' (tracheostomy removal).
