The risk of an electrical shock to the rescuer. Speaking as a lifeguard, the pool decks are typically wet, and if the AED's shock travels through the water on the pool deck, it can pose a threat to the rescuer.
AED is the acronym used to refer to an automated external defibrillator, which is equipment that allows the application of an electric current to a patient's heart. And it aims to prevent your death from cardiac arrest. The External Automated Defibrillator (AED), a device used in this procedure, is also indicated to treat arrhythmias, atrial or ventricular fibrillation and tachycardia.
As the AED works by applying a lightning strike, it is important that the victim is transported to a dry place (and has a dry body) before the AED is used. This is because, as water is a conductor of electricity, its presence in the use of AED may increase the risk of electric shock to the victim and the rescuer.
