What is critical to ensure before using AED pads on any patient?

Ensuring that no one is touching the patient during the delivery of a shock is crucial for the safety and effectiveness of using an Automated External Defibrillator (AED). If someone is in contact with the patient while the shock is delivered, they could also receive an electric shock, which poses a significant risk to both the rescuer and the bystanders. The shock is intended to restore a normal heart rhythm in the patient experiencing cardiac arrest, and any physical contact could divert the electrical energy away from the patient's heart, potentially rendering the defibrillation ineffective.

While it's important that the AED is fully charged, that pad placement is correct, and that the patient’s level of consciousness is assessed, these factors do not directly address the immediate safety concerns associated with the defibrillation process. Ensuring everyone is clear from the patient allows for the AED to deliver the shock safely and effectively, maximizing the chances of a successful outcome.
