A defibrillator or AED is a portable device that checks the heart’s rhythm and sends a shock to the heart to restore a normal rhythm. The device is used to help people having sudden cardiac arrest. Early defibrillation combined with CPR can improve survival rates to as high as 74% when defibrillation is provided within three minutes of collapse. For every minute that is wasted, the chance of survival decreases 7-10%.
Sticky pads with sensors and electrodes, are attached to the chest of someone who is having cardiac arrest. The sensors send information about the person's heart rhythm to a computer in the AED. The computer analyzes the heart rhythm. If needed, the electrodes deliver the shock.
