    Date Published: November 11, 2026

    When someone suddenly collapses from cardiac arrest, the people nearby may be the first ones able to help. You do not have to be a healthcare professional to use an automated external defibrillator (AED). Coworkers, teachers, coaches, parents and other bystanders can help during a cardiac arrest emergency by retrieving and using an available AED.

    Using medical equipment in an emergency may feel intimidating. CPR/AED training can help you feel more prepared, but lack of training should not stop you from acting. Call 911, start CPR and use an available AED to provide critical help until emergency medical services arrive.

    Can Anyone Use an AED?

    Anyone can use an AED during a sudden cardiac arrest emergency. AEDs are designed for both trained and untrained responders and provide simple prompts that guide users through the process. Responders may include employees, teachers, coaches, parents, bystanders and security personnel.

    Do You Need Training to Use an AED?

    Formal training or certification is not required to use an AED; however, training can help responders become familiar with recognizing cardiac emergencies, performing CPR, placing AED pads and working with other responders before an emergency occurs.

    Benefits of Learning CPR and AED Skills
