When using a resuscitation mask on a 6-year-old, how should the lifeguard position the child's head to open the airway for ventilations?

To effectively use a resuscitation mask on a 6-year-old, positioning the child’s head in a slightly past-neutral position is essential for opening the airway and facilitating ventilations. This head position helps to align the airway structures, reducing the risk of airway obstruction and ensuring that the air delivered through the resuscitation mask reaches the lungs efficiently.

When the head is positioned slightly past neutral, the lifeguard allows for proper alignment of the airway without overextending the neck. This is particularly important in younger children, as they have different anatomical considerations compared to adults. A fully tilted back position can lead to hyperextension of the neck, which may obstruct the airway rather than open it. A flat position does not provide the necessary alignment to effectively deliver air. Turning the head to the side can also compromise the airway by preventing direct access for ventilation.

Thus, slightly past-neutral positioning is the best practice, as it combines safety and effectiveness in providing ventilations.
