Anteroposterior AED pad placement is when one pad is placed on the front of the chest and the other pad is placed on the back. This placement is often used for infants and young children. Here are some additional details on AED pad placement:

• Anterior-posterior (AP) pad placement: This is when the AED pads are placed on the chest, one on the right side and one on the left side. This position is often used for adults and children over the age of eight.

• Anterolateral placement: This is when one pad is placed on the right side of the chest (just below the collarbone) while the other pad is put on the lower part of the left chest wall or a few inches below the left armpit. This position is often used for adults and children over the age of eight.

It is important to follow the instructions provided by the AED and any additional guidelines provided by a healthcare provider or trained medical professional.
