During AED analysis, what must be done according to BLS guidelines?

During AED analysis, it is essential to ensure that everyone is clear of the area where the AED is being used. This is critical because the AED will analyze the heart rhythm to determine if a shock is needed. If people are touching the patient or are in close proximity, it could interfere with the analysis, and there's also a risk of causing harm if a shock is delivered while someone is in contact with the person receiving care.

Clearing the area not only enhances the accuracy of the AED's function but also promotes safety for both the patient and bystanders. By having everyone step back, it allows for a focused environment where the AED can operate effectively, and medical responders can provide the necessary care without hazards. This emphasis on safety and accuracy aligns with the BLS guidelines to ensure the best possible outcome for the patient in a cardiac emergency.
