Where should back blows be delivered on a choking person?

Back blows should be delivered between the shoulder blades on a choking person because this area is effective for creating a forceful impact that can help dislodge an object blocking the airway. When delivered correctly, back blows utilize the natural positioning of the person, typically while they are leaning slightly forward, allowing gravity to assist in removing the obstruction. This technique is part of the recommended first-aid measures for choking, which also includes abdominal thrusts. By targeting the upper back region, rescuers can generate sufficient momentum to help alleviate the choking incident effectively.
