If an AED is needed on someone who has been submerged in water, what should you do?

When someone has been submerged in water and requires the use of an Automated External Defibrillator (AED), the most appropriate course of action is to pull them out of the water and wipe their chest. This is crucial because water can conduct electricity, potentially interfering with the AED’s operation and increasing the risk of electric shock to both the patient and the rescuer.

By removing the person from the water, you mitigate the risk of shock and ensure that the AED pads have good contact with the skin. Wiping the chest to remove any moisture also helps to ensure the AED functions effectively, as the pads need to adhere properly for the defibrillation process to occur successfully.

The other options present various risks or impracticalities. Leaving someone in the water while attempting to use an AED poses a danger due to potential electrical hazards. Using the AED without pulling them out doesn't address the moisture issue, and waiting for them to dry before applying the AED could result in a delay that might be detrimental. Therefore, removing them from the water and preparing their chest is the safest and most effective approach.
