Which of the following best describes a proper back blow technique for a choking child?

The correct answer highlights the importance of delivering effective back blows in a specific manner to aid a choking child. By delivering forceful blows between the shoulder blades, you create enough pressure to potentially dislodge the obstruction causing the choking. This technique is particularly crucial because the forceful blows utilize gravity and the child's own body weight to help expel the object.

Proper back blows should be delivered with a firm and confident motion, aimed at the midline of the back just between the shoulder blades. This approach maximizes the likelihood of clearing the airway while minimizing the risk of injury. Ensuring that the blows are forceful is essential, as gentle taps may not create sufficient force to effectively remove the object.

Using the back of the hand, administering soft taps, or trying to strike the back with both hands lacks the necessary strength and focused technique required for successful intervention in a choking emergency.
