Where's your AED?
Each year it is estimated that as many as 450,000 Americans suffer from sudden cardiac arrest and that 90-95 percent of people suffering SCA will die. In many of these cases, electrical shocks delivered to the heart within four minutes of the onset of abnormal heart function produce as high as a 70 percent chance of survival.
Unfortunately, after ten minutes without treatment, the survival rate for someone suffering from sudden cardiac arrest drops to only 2 percent. Sudden cardiac arrest can occur during a heart attack, electrocution or asphyxiation, caused by inadequate oxygen in the work environment, such as in a confined space.
An automated external defibrillator (AED) is a small device that can help save the life of somebody in sudden cardiac arrest. It is often no bigger or heavier than the average laptop computer, and delivers a small but powerful shock that may be able to reset the heart rhythm of somebody in cardiac arrest. Once the adhesive pads are placed on the victim, the AED can monitor the person’s heart rhythm, determine if they are in need of a shock, and instruct the user to administer a shock or CPR accordingly. A conveniently located AED and trained responders in your workplace could mean the difference between life and death for an employee.
Early defibrillation means having immediate access to a properly working AED. This allows trained lay rescuers to give a potentially lifesaving electrical shock to the victim’s heart during a cardiac arrest.
Organizations need to consider who is responsible for AED program oversight. This responsibility usually rests with staff members who already have safety as part of their job description. However, specific training for these individuals on first-aid, CPR and AED use is critical. Organizations must also determine if any non-safety staff members will have a responsibility to respond. If so, these individuals will also require proper training.
Even though all AEDs work in roughly the same manner, there may be small differences between different brands. Because of these small differences, you should train those responsible for operating AEDs in your organization to use the specific AED brand in your facility before they attempt a lifesaving measure using an AED. Persons responsible for administering AEDs should also receive CPR training, a critical part of the cardiac chain of survival discussed below, and first-aid or lifesaving measure training. As in the case of any emergency, train all employees on the specific reporting and emergency action procedures at your site.
AEDs are not a replacement for professional medical help. Only perform these lifesaving measures after you have contacted EMS. Provide the victim with AED treatment while waiting for EMS to arrive.
Recognized by the American Red Cross, the American Heart Association, hospitals and EMS personnel, the Cardiac Chain of Survival is a series of four steps for treating victims of sudden cardiac arrest:
- Early access to care â€” call 911 or other emergency number
- Early cardiopulmonary resuscitation (CPR)
- Early defibrillation (use of AED)
- Early advanced cardiac life support, as needed.
OSHA recommends the following guidelines for placement of AEDs within your organization:
- AEDs should be conveniently installed to ensure response within 3-5 minutes;
- Areas where many people work closely together, such as assembly lines and office buildings;
- Close to a confined space;
- Areas where electric-powered devices are used;
- Outdoor worksites where lightning may occur;
- Health units where workers may seek treatment for heart attack symptoms;
- Company fitness units and cafeterias;
- Remote sites, such as off-shore drilling rigs, construction projects, marine vessels, power transmission lines and energy pipe lines.
Persons responsible should review procedures for use every three to six months. Follow the steps of the chain of survival to ensure the victim receives proper treatment.
