Final answer:
The 'stand clear' prompt from an AED means that all individuals should avoid touching the patient or the AED because it is about to deliver an electric shock to the patient's heart.
Step-by-step explanation:
When an Automated External Defibrillator (AED) prompts users to 'stand clear,' it is instructing them to not touch the patient or the device. This is because the AED is about to administer an electric shock to the patient's heart. The reason for this clear space is to prevent anybody else from being shocked and to ensure that the AED can analyze the patient's heart rhythm accurately without interference. It's crucial that this instruction is followed immediately to avoid any injuries and to give the patient the best possible chance of recovery. In addition, CPR (cardiopulmonary resuscitation) is often recommended before the use of an AED to increase the chances of a successful resuscitation.
