How should postanesthesia airway compromise be monitored after extubation?

• A. No monitoring required after extubation if the patient appears stable.
• B. Monitoring focus on heart rate and blood pressure only.
• C. Pulse oximetry alone is sufficient for post-extubation monitoring.
• D. Continuous respiratory monitoring, capnography if indicated, observation for stridor or obstruction, ensure airway patency and oxygenation.

Answer: (D)

After extubation, airway compromise can develop quickly as sedation wears off and airway patency changes. The best monitoring approach keeps a close eye on ventilation and airway status: continuous respiratory monitoring to track rate, effort, and pattern; capnography to measure end-tidal CO2 and detect hypoventilation or obstruction in real time; careful observation for signs of airway narrowing such as stridor or obstruction; and proactive steps to maintain airway patency and oxygenation, including positioning, suctioning secretions, and providing supplemental oxygen as needed. This comprehensive approach catches problems early, even if oxygen saturation remains normal initially. Relying only on heart rate and blood pressure or on pulse oximetry alone can miss evolving ventilation problems, since a patient can maintain adequate SpO2 for a time despite hypoventilation or partial airway obstruction.
