Suspected difficult laryngoscopy Suspected difficult ventilation with face mask / SGA Significant ↑ risk of aspiration Increased risk of rapid desaturation Suspected difficult emergency invasive airway Suspected difficult ventilation with face mask/ SGA Suspected difficult ventilation with face mask/ SGA Suspected difficult ventilation with face mask/ SGA Suspected difficult ventilation with face mask/ SGA Awake intubation Intubation after induction of general anesthesia YES NO YES NO Optimize O2 throughout Airway approached by noninvasive intubation Invasive airway access Success Fail Consider feasibility of other options Cancel case Invasive airway access Confirm with exhaled CO2 Initial intubation attempts successful Initial intubation attempts unsuccessful Limit attempts: consider calling for help Face mask ventilation adequate Face mask ventilation inadequate Consider/attempt SGA SGA adequate Not adequate or feasible Nonemergency pathway: -ventilation adequate -intubation unsuccessful Emergency pathway: -limit attempts -note passage of time Limit attempts: consider waking the patient Consider alternative intubation approach, invasive access, or other options Call for help Emergency noninvasive airway ventilation Successful ventilation Fail Fail or deterioration in ventilation Success Emergency invasive airway access
