Final answer:
Before using an AED, it may be necessary to shave or trim the hair on a victim's chest to ensure proper pad adhesion and electrical conductivity. CPR is also often recommended before AED use.
Step-by-step explanation:
Before applying the Automated External Defibrillator (AED) pads to a victim with a hairy chest, it may be necessary to shave or trim the hair in the area where the pads are to be placed. This is because excessive hair can interfere with the proper adhesion of the pads, leading to poor conductivity of the electrical charge that is necessary to help the heart regain its normal rhythm in cases of cardiac arrest or ventricular fibrillation. CPR (cardiopulmonary resuscitation) is also recommended in many cases before using an AED to provide the best chance of survival.
