When using an AED, what should you do immediately before pressing the shock button?

Before pressing the shock button on an AED, it is crucial to ensure that all rescuers and bystanders are a safe distance away from the patient. This is paramount because the shock delivered by the AED can potentially affect anyone in close proximity. Making sure that everyone stands clear not only protects them from accidental shock but also ensures that the AED can operate without interference.

The AED will typically prompt the user to check that the area is clear before delivering a shock, emphasizing the importance of safety during this critical moment of resuscitation. Taking this precaution helps to ensure the effectiveness of the shock and the safety of everyone involved in the rescue effort.
