Visual aids for pediatric airway management

Four basic types of visual aids are used for teaching airway management and decision-making in simulated as well as in real clinical situations: universal algorithms, sets of limited algorithms, concept-based cognitive aids, and checklists. The first three may represent an evolution in the understanding of the role of human error in both successful and failed airway management. Complex visual aids such as the American Society of Anesthesiology difficult airway algorithm may be more useful for teaching, while graphic cognitive aids like the Vortex may be more helpful for decision-making under stress. Not surprisingly, there is a lack of outcome studies, although some cognitive aids have been evaluated in simulation settings.
