This is essential for many emergency medical services that may be responding to significant cases of trauma and injury. In addition most portable AED defibrillators also have internal memories that record and time stamp all readings, actions and electronic monitoring that the equipment does. This information can then be accessed via those ports to assist doctors and emergency medical staff when they arrive on the scene. What training do I need to have to use a portable AED defibrillator? The whole purpose of having fully automated portable AED defibrillators is that the person using the equipment doesn't need specific medical training, although if trained individuals are present it is recommended that they use the equipment. All that is required is that the individual operating the equipment attach the self-adhesive, self-gelled pads to the victim's chest. The machine then reads the heart's electric impulses and determines if a shock needs to be administered to regulate the heart rhythm. When the machine determines that the heart needs to be shocked, it will signal the battery that will immediately charge the system then administer the therapeutic shock. The individual operating the system does not have to make this decision, nor does he or she have to push a button or tell the machine what to do in any fashion. The portable AED defibrillator then continues to monitor the heart's response and will subsequently determine if any further impulses are needed. Can I get training in using a portable AED defibrillator? Yes, many organizations that offer first aid certification and classes also include portable AED defibrillator training in their workshops. Generally organizations such as the American Safety and Health Institute, the American Red Cross, and the American Heart Association offer trainings. In addition manufacturers of the portable AED defibrillators typically provide in house training or provide a DVD of how to use the equipment.
