Final answer:
AED pads for anteroposterior placement should be put on the right side of the chest below the clavicle and on the left side of the back below the shoulder blade and to the left of the spine.
Step-by-step explanation:
When using an automated external defibrillator (AED) for anteroposterior placement on adults and children 8 years and older, the AED pads should be placed as follows: one on the right side of the chest, just below the clavicle, and the other on the left side of the back, just below the shoulder blade and to the left of the spine. This placement allows the electrical current to pass through the heart, which can be a lifesaver for someone experiencing sudden cardiac arrest or a heart attack that has led to ventricular fibrillation. It is important to note that CPR is often recommended before using an AED.
