When an individual goes into cardiac arrest, his or her heart stops pumping blood, a problem which may be caused by uncoordinated electrical activity or arrhythmia within the heart. Administrating an electrical shock with a defibrillator often helps the heart to begin beating efficiently again and restore its proper rhythm.

AEDs, or automated external defibrillators, were developed in an effort to minimize deaths caused by fibrillation. Access CardioSystems, a medical business opened in 2000, developed the AccessAED specifically for laypeople and the general public to use in the event of a cardiac emergency. Access CardioSystems engineered its AEDs to be user-friendly in an effort to minimize and help to prevent deaths. The system requires no formal medical training to operate because the directions can easily followed in the event of an emergency.

AED devices provide prompts that inform the user to attach electrodes to the subject. Once attached, the electrodes analyze the subject’s cardiac rhythm to determine whether a shock is necessary. If so, the user is prompted to press a button that delivers a shock. The subject is then reanalyzed by the AED to determine if an additional shock is needed. If not, the device will prompt the user to check the subject’s pulse. In many cases, users should perform CPR in conjunction with the AED’s functions.
