When using an AED, what is a crucial action to take before delivering a shock?

Ensuring that everyone is standing clear before delivering a shock with an AED is crucial to prevent accidental injury to bystanders and responders. The AED delivers a high-energy shock to the heart in an attempt to restore a normal rhythm in the case of cardiac arrest. If anyone is touching the patient or is too close, they could also receive an unintended shock, which may lead to serious injury.

By calling out for everyone to stand clear, you help ensure a safe environment for the defibrillation process. This action is an essential part of using an AED, as safety for all individuals involved, including the patient and responders, is paramount during resuscitation efforts.

Options involving checking for a pulse, performing additional chest compressions, or assessing for normal breathing are important steps in the overall resuscitation sequence but are not specific actions that need to be done immediately before administering a shock with an AED. The focus at that moment should be on ensuring safety first.
