Can you use a defibrillator on a metal surface?
A defibrillator, or AED (automated external defibrillator), is a life-saving device which delivers an electrical shock to the heart during a cardiac arrest.
There are many myths about using a defibrillator. Many people believe that you can’t use a defibrillator in any situation where the electrical shock might be transmitted.
It is perfectly safe to use a defibrillator on a metal surface – providing the pads have been applied correctly and the chest is dry there is minimal risk.
Modern defibrillators modify the shock provided to the patient depending on their electrical resistance (ie, how big / small / fat / thin they are) so the shock delivered is not excessive.
