The appropriate technique for administering back blows to a responsive infant with an obstructed airway involves using the heel of the hand between the scapulae. This method is effective because it allows for a firm yet controlled strike that can generate enough force to help dislodge an object blocking the airway. The positioning and use of the heel of the hand also ensure that the blows are delivered to a specific target area, which maximizes the likelihood of success without causing further injury to the infant.

The heel of the hand provides a blunt surface that is safer for the delicate anatomy of an infant compared to other techniques that may involve more risky angles or positions. Proper technique not only increases the chances of clearing the airway obstruction but also minimizes the risk of harm during the delivery of back blows. Thus, this method aligns with the guidelines set by organizations like the American Red Cross for performing basic life support in infants.
