The automated external defibrillator is a portable, electronic medical device that was designed to allow minimally trained people to provide lifesaving defibrillation to victims of sudden cardiac arrest. When electrodes are attached to the chest of a cardiac arrest victim, the AED immediately analyzes the heart to check for cardiac arrhythmias including Ventricular Tachycardia (V-Tach) and Ventricular Fibrillation (V-Fib). In these two states, the heart acts erratically and cannot the necessary blood to the brain and extremities of the body.
When the AED detects one of these cardiac arrhythmias, it send a shock between 150 and 360 Joules through the chest to the heart. The shock depolarizes the heart major muscles and eliminates the fatal arrythmia by stopping the heart. The heart then resets its natural pacemaker and begins to beat normally again.
When it comes to sudden cardiac arrest, timing is of the essence. The American Heart Association’s Chain of Survival lists 4 steps that must happen in less than 5 minutes for a victim of sudden cardiac arrest to survive the event, and one piece of this chain requires “early defibrillation”. Without early defibrillation, a victim of SCA will not survive.

To provide the best opportunity for survival, each of these four links must be put into motion within the first few minutes of SCA onset:
When each link in the chain works successfully, the chance of surviving SCA increases greatly.

The value of having an AED on the premises cannot be overstated.
The Zoll AED Plus is one of several excellent AEDs available today. The following pictures and information will explain this specific device, however, all AEDs are based on the same basic technology, with various specific features that can be tailored to the setting the AED will be in.
Size: H x W x D – 5.25” x 9.50” x 11.50”
Weight: 6.7 lbs
Batteries: replaceable 123 Lithium
Device Classification: Class II
The Zoll AED Plus CPR-D padz is a one size fits all one piece electrode that can accommodate the wide range of patients sizes and shapes, and is extremely simple to use while in what can be a stressful rescue mode. This one piece design enables the user to quickly get the pads placed by using the easily remembered CPR landmark (the sternum) as the key placement cue. In addition, the CPR-D pads actually provide REAL CPR assistance with feedback on CPR compression depth and rate. This feature is very beneficial to minimally trained people who may find themselves suddenly in a situation of providing lifesaving care to a victim of cardiac arrest.
Once opened, with electrodes placed on the victim’s check, the AED gives a shock to reset the heart for 2 of the most common rhythms causing heart issues (pulseless ventricular tachycardia (VT) and ventricular fibrillation (VT or V-Fib).
The pads are placed so that the device can send a shock through the chest into the heart, and thereby resetting the heart rhythm.
