AED text screens for the hearing impaired: Cardiac Science for the week of August 17

Heartsafe news: Our weekly update on what’s happening in the world of heart safety and noninvasive cardiology

Text screens and text prompts extend AED usability

For most purchasers, clear, comprehensive audio prompts are among the most important factors for them to consider when choosing an automated external defibrillator (AED).

But there are reasons why a text screen with step-by-step text prompts, like the one on thePowerheart G3 AED, is important, too.

At schools for the deaf, and in workplaces where many employees are hearing impaired, a rescuer is very likely to be someone who will use text rather than audio prompts. There are also many instances in which easily readable text prompts supplement the audio instructions. These include rescues in environments where loud noise drowns out audio prompts.

Cooling therapy helps cardiac arrest survivors

The American Heart Association reports that cooling unconscious cardiac arrest survivors can increase survival rates. This relatively new treatment has a cost effectiveness comparable to other widely accepted treatments for cardiac arrest survivors, according to a study that appears in Circulation: Cardiovascular Quality and Outcomes.

Therapeutic hypothermia is the only post-resuscitation therapy shown to improve both survival and reduce disability after cardiac arrest, according to the study’s lead author, Raina M. Merchant, M.D., an emergency medicine physician at the University of Pennsylvania School of Medicine.

The treatment has been recommended by the American Heart Association since 2003, but has not been widely adopted. The research study was conducted to determine if cost was a barrier to widespread use of cooling treatment.

With therapeutic hypothermia, a patient’s body temperature is cooled and the patient is monitored so that their internal body temperature remains between 32 and 34 degrees centigrade (89.6 to 93.2 degrees Fahrenheit) for at least 12 to 24 hours. There are a variety of technologies used to do therapeutic cooling; the study focused on the use of cooling blankets.

Albany County requires AEDs for sports facilities reports that Albany County, New York, has a new New York AED law, one that will require area sports facilities to have defibrillators on site. The new law applies to indoor and outdoor sports venues where more than 500 people are present over a 24-hour period. It expands county AED requirements, which previously applied only to health clubs in the county. You can reach Cathy Fisher at Cardiac Life Products for more information at 866.405.6212.

Campground AEDs may become a trend

The Portland (Maine) Press Herald reports that a family campground in Old Orchard Beach, Maine, may have started a trend in campground AEDs by installing two devices and training staff their use. One AED at the Powder Horn Family Campground is by the pool, and the other near the campground office.

The executive director of the Maine Campground Owners Association, Rick Abare, told the paper that the association currently encourages campgrounds to train their workers in CPR. Powder Horn may be the first to install defibrillators, but Abare said he thinks AEDs are likely to be the next trend in safety equipment for the campground industry.

American Heart Association iPhone app includes CPR/AED information and video


Step-by-step CPR and AED information are included in this iPhone app from the American Heart Association

A new iPhone app, created for the American Heart Association (AHA) by Jive Media, enables people to carry the most up-to-date first aid, CPR, and AED information with them on an iPhone or iPod Touch. Users can review text, illustrations, and video at their convenience, or access information quickly in an emergency.

The CPR/AED section of the app features illustrations and videos, including video of a simulated AED rescue. It shows a rescuer calling for an AED, administering CPR, applying AED pads and then following AED instructions to clear the victim and administer a shock. There are also text instructions for conducting an AED rescue in special situations, including situations in which a victim is lying in water, or has just been pulled from water and is still damp.

The application also allows users to create portable electronic health records (such as allergies, blood type, and medications) for themselves and family members.
