Final answer:
If only pediatric pads are available, they may be used on an adult in an emergency by placing one pad on the chest and one on the back.
Step-by-step explanation:
In situations where only pediatric pads are available, and an adult is in need of an Automated External Defibrillator (AED), these pads may be used as a last resort. It is critical, however, to ensure that they are placed correctly. For adults, one pad should be placed on the center of the chest (sternum) and the other on the back, between the shoulder blades to ensure the electric current passes effectively through the heart. Pediatric pads are designed to administer a lower level of shock than adult pads, but when adult pads are not available, using pediatric pads is better than not attempting defibrillation at all. Always follow the specific instructions provided by the AED unit and seek professional medical help as soon as possible.
