What is the best indicator of extubation readiness?

• A. Adequate airway protection and mental status; no excessive secretions
• B. Requires only normal oxygenation
• C. OK to extubate if sedation is low
• D. Extubation readiness is determined by ABG only

Answer: (A)

Extubation readiness is best predicted by the patient’s ability to protect the airway and handle secretions. If someone can’t reliably cough, swallow, or clear secretions, removing the tube risks aspiration, airway collapse, or immediate respiratory failure—regardless of how well their oxygenation looks on paper. Mental status matters too because alert, cooperative patients are better able to maintain their airway after extubation.

Oxygenation or ventilation alone doesn’t guarantee safety if airway reflexes are impaired. Sedation level or an ABG can be normal while the patient still lacks adequate airway protection, so they don’t fully capture readiness. In practice, the strongest signal is adequate airway protection with an appropriate mental status and manageability of secretions, often alongside a successful spontaneous breathing trial and acceptable oxygenation on minimal support.
