Final answer:
To use an AED on an infant, place one pad on the sternum and another between the scapulae on the back. For very small infants, a single pad may be used in the center of the back. Correct AED pad placement and CPR technique are vital and proper training is recommended.
Step-by-step explanation:
When using an Automated External Defibrillator (AED) on an infant, it is crucial to place the pads correctly to effectively deliver the shock needed to restart the heart. The correct placement is one pad on the middle of the chest on the sternum, and the other pad on the back between the scapulae. For very small infants, if the pads risk touching each other, a single pad can be used placed in the center of the back between the shoulder blades. This ensures the electric current passes through the heart. CPR, which should be rendered prior to AED use, supports the flow of blood until the heart resumes beating. It involves applying pressure to the sternum, ideally between the T4 and T9 vertebrae as depicted in Figure 19.3, to compress the heart and maintain circulation.
Proper training is essential in the application of both CPR and AED to prevent additional harm to the patient. CPR courses include practice of the technique on a mannequin and are available through a variety of venues, such as colleges, hospitals, the American Red Cross, and some commercial companies.
