When should an AED not be used?

An AED, or Automated External Defibrillator, should not be used in wet conditions because moisture can conduct electricity, increasing the risk of electrical shock to both the patient and the rescuer. If the patient is lying on a wet surface, such as during rain or in a flooded area, it's essential to move the individual to a dry area if possible before using the AED. This helps ensure the safety of everyone involved and enhances the effectiveness of the device.

In contrast, if the victim is conscious, they do not require defibrillation, as AEDs are intended for individuals who are unresponsive and not breathing. Using an AED when the victim is conscious or in a dry place does not present the same risks as wet conditions do. The reference to low voltage is also misaligned with normal conditions of an AED; they are designed to operate under a wide range of conditions, including variations in power supply, as long as safety protocols are followed. Thus, wet conditions present the primary concern, marking them as unsuitable for AED usage.
