Which type of communication should be used if AED prompts cannot be heard?

Using someone to relay the prompts from the AED ensures that the rescuer can receive the critical information needed for effective use of the device, especially in a noisy environment where prompts might not be audible. This method allows for clear communication of the specific instructions given by the AED, ensuring that the rescuer can respond accurately and timely to the prompts provided, while also maintaining focus on the patient.

While other methods of communication may be useful in different contexts, relaying the prompts through a designated person allows for immediate reinforcement of the AED's instructions without interruption of the rescue process. It also strikes a balance between maintaining situational awareness and facilitating effective lifesaving measures.
