Before using an Automated External Defibrillator (AED), it is crucial to ensure the victim is on a firm, dry surface and to check for responsiveness. This step is foundational because it confirms that the individual requires an intervention and is not responsive to stimuli, which may indicate cardiac arrest. Placing the victim on a firm surface is vital to allow the AED to analyze heart rhythms correctly and provide effective defibrillation if necessary. Checking for responsiveness also helps to ascertain the need for immediate resuscitation efforts, including CPR.

While other actions related to AED usage are important, such as checking the AED battery and pads, calling for emergency help, or beginning CPR, they typically follow the initial assessment of the victim. Ensuring the safety and proper condition of the environment and verifying the absence of responsiveness are essential first steps in preparing to use the AED effectively.
