Extubation Readiness and Procedure

Key Points

• Extubation is the final step in liberation from invasive mechanical ventilation.
• Readiness assessment must prioritize airway protection and airway patency.
• Key source-based criteria include adequate consciousness (GCS greater than 8), effective cough strength, secretion assessment, and cuff-leak evaluation.

Equipment

• Airway management setup for planned extubation and immediate reintubation backup
• Oxygen and monitoring equipment for post-extubation surveillance
• Suction equipment for secretion management
• Rapid-response personnel support when difficult airway risk is present

Procedure Steps

1. Confirm patient has passed spontaneous breathing trial and is being evaluated for extubation suitability.
2. Reassess ability to protect and maintain a patent airway before tube removal.
3. Assess consciousness level; GCS greater than 8 indicates higher likelihood of extubation success.
4. Evaluate cough strength and obtain objective measures when available.
5. Recognize weak cough or MIP greater than -20 cm H2O as strong risk factors for extubation failure.
6. Assess respiratory secretion volume and thickness.
7. Perform cuff-leak test to evaluate airway patency.
8. Review prior airway anatomy/intubation difficulty and prepare additional equipment/personnel when difficult airway risk exists.
9. Proceed with extubation once criteria are acceptable and contingency resources are in place.
10. Monitor closely after extubation for airway compromise, secretion intolerance, and respiratory deterioration.

Common Errors

• Proceeding without airway-protection assessment → increased immediate extubation failure risk.
• Ignoring weak cough or high-risk MIP pattern → delayed recognition of likely failure.
• Insufficient difficult-airway backup preparation → unsafe response capacity if reintubation is needed.
• Limited post-extubation surveillance → delayed rescue in early deterioration.
