When giving back blows to an infant, where should the responder aim?

The correct approach when giving back blows to an infant is to aim between the infant's shoulder blades. This area is targeted because it is where the most effective force can be applied to help dislodge an obstruction, such as food or a small object, from the airway. By delivering a firm blow in this specific spot, you create a rapid pressure change in the chest cavity that may allow the object to be expelled.

The technique involves positioning the infant face down on your forearm, with their head slightly lower than their chest, which helps gravity assist in the removal of the blockage. Positioning the infant this way is critical for maximizing the effectiveness of the back blows.

Other possible locations, such as the head, the lower back, and the base of the skull, do not provide the same mechanical advantage for dislodging an airway obstruction. It's important for responders to understand the correct technique and target area to ensure they are performing the intervention effectively and safely.
