When using an AED on an infant, the pads should be placed in a way that avoids contact with each other and provides effective shock delivery. The recommended placement for the pads on an infant is:
One pad on the center of the chest and the other pad on the center of the back.
This is often referred to as the "anterior-posterior" placement, and it helps to avoid interference between the pads and allows for better current flow through the heart. Always ensure to follow the specific instructions provided with the AED device being used, as some devices may have specific guidelines for pediatric patients.
