What positioning is most effective for opening the airway in a child who is unconscious?

The most effective positioning for opening the airway in an unconscious child is to tilt the head slightly past neutral. This posture helps to align the airway in a way that reduces the likelihood of airway obstruction, particularly by the tongue, which is a common issue in unconscious individuals.

In this position, the airway opens more efficiently, allowing for better airflow and easier access for any necessary interventions, such as ventilation. The slight tilt encourages proper alignment of the head and neck, crucial for maintaining an open airway, especially in a child where anatomical differences may affect airway patency.

Other positions, such as keeping the head upright or extending the head back too far, may compromise airway function or lead to further obstruction. Maintaining a neutral position generally does not provide the optimal degree of airway openness necessary in emergencies.
