Extubation Criteria

Introduction

Below is a checklist to follow when considering extubating a patient.

Approach

Airway

Ensure the patient will be able to protect their own airway and that airway recapture is possible

  • protective reflexes are present (cough, gag)
  • cuff leak is present (generally after long cases, surgeries near the neck, or Trendelenburg position)
  • reintubation or ventilation is feasible (the difficulty of intubation can dictate how conservative extubation must be)

Breathing

Ensure the patient's respiratory drive is adequate for maintaining oxygenation and ventilation

  • the patient is triggering the ventilator
  • the patient is drawing adequate tidal volumes and minute ventilation (this will be related to the amount of assistance the ventilator is delivering)
  • the patient is triggering the ventilator at an appropriate respiratory rate (often targeting RR 10-12 at the end of a case)
  • the patient has adequate gas exchange

Circulation

Ensure that the patient's hemodynamics are stable enough for extubation

  • change from positive pressure ventilation to negative pressure will be tolerated well
    • especially important in cardiac pathology and pulmonary hypertension
  • added work of breathing will be tolerated hemodynamically

Disability/Drugs

Ensure the patient has a level of consciousness that is amenable to extubation. Similarly, ensure there are no drugs in the patient's system that may cause them to fail extubation

  • reversal of neuromuscular blockers (train of four > 90%)
  • adequate analgesia on board
  • condition requiring intubation has been resolved (if intubated in a non-elective setting)
  • there is no patient condition that requires control of ventilation (ex. TBI protocol necessitates avoiding hypercapnia)
