What is the first step in using an Automated External Defibrillator (AED)?

Turning on the AED is indeed the first crucial step in the use of this lifesaving device. Once the AED is powered on, it will provide audio and visual prompts that guide the responder through the subsequent steps, ensuring that even those with minimal training can operate it effectively. The activation of the AED initiates its internal checks and prepares the device for the next actions, such as applying the pads and analyzing the heart rhythm.

Starting with the device powered on means that it can quickly respond to the situation and provide necessary instructions. This promotes a streamlined approach to treating a victim who may be experiencing sudden cardiac arrest. Every second counts in such emergencies; thus, early activation is critical for enhancing the chances of a successful outcome.
