Table 1 shows a simplified version of all the previously described algorithms.

Further laryngoscopy attempts may use different laryngoscopes and simple aids such as a GEB.

Maintenance of oxygenation is the over-riding priority at all times.

Action after initial failed attempt to intubate

Can’t intubate: Elective case

Can’t intubate: Emergency case

Can’t intubate: Can’t ventilate

4 (maximum) intubation attempts

2 (maximum) intubation attempts

2 (maximum) further intubation attempts

Attempt oxygenation by FM or LMA

Secondary attempt using additional equipment (ILMA etc.)

Wake patient up unless surgery immediately life-saving

Cricothyroidotomy and high or low pressure ventilation
