ZOLL Medical Now Shipping AHA 2005 Guidelines-Compliant AED Plus, Offering "Real CPR Help" for Chest Compressions



June 21, 2006—CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and related software solutions, today announced that it is now shipping a new version of the ZOLL AED Plus™ with Real CPR Help™ that fully complies with the 2005 American Heart Association (AHA) Guidelines. ZOLL is unveiling this device in Booth #23 at the upcoming 2006 Emergency Cardiovascular Care Update Conference to be held from June 22 through June 24 in Orlando, Fla.

The AED Plus now follows the newly recommended compression-to-ventilation ratio of 30 compressions to two breaths. It also allows one defibrillating shock, if needed, followed by a two-minute CPR interval. These enhancements are meant to help rescuers deliver high-quality, effective CPR by delivering more chest compressions while limiting interruptions.

The AED Plus also allows rescuers to see and hear how well they perform the rate and depth of CPR chest compressions. Because only about half of sudden cardiac arrest (SCA) victims are typically in a shockable rhythm (known as ventricular fibrillation), this real-time feedback mechanism, known as Real CPR Help, makes the ZOLL AED Plus the only AED that can help lay rescuers assess and treat nearly every SCA victim, making it the only Full-Rescue AED available today.

Along with software changes that make the AED Plus Guidelines-Compliant, the AED Plus uses a one-piece electrode for easier positioning on the victim’s body (versus the traditional two electrodes, which can be challenging to place properly). This special electrode set, known as the CPR-Dpadz, includes a sensor that measures the rate and depth of chest compressions. The AED Plus converts compression data from the CPR-Dpadz and provides visual and audible feedback, such has “Push Harder” or “Good Compressions,” as needed. In this manner, rescuers have ongoing feedback that tells them—via audible and visual prompts—how well they are delivering chest compressions, thus promoting the goal of circulating blood to help sustain the life of an SCA victim.

In addition to assisting during a cardiac arrest event, the AED Plus also captures all critical data during a rescue. This includes:

- The patient’s complete ECG that acts as a timeline for the entire rescue event;
- A readout of the frequency and depth of CPR chest compressions; and
- Data points showing when defibrillation shocks are given and when audible prompts (e.g., “Push Harder” or “Good Compressions”) are communicated to the rescuer.

This information allows rescuers to understand and evaluate how well they performed CPR and to help improve overall performance.

According to the AHA Guidelines,* evidence from two clinical studies show that chest compression rate during unprompted CPR is frequently inadequate in both out-of-hospital and in-hospital settings. The Guidelines also noted data that showed the critical role of early, high-quality CPR in increasing cardiac arrest survival rates. Furthermore, additional data showed that few victims of cardiac arrest receive CPR and even fewer receive high-quality CPR. Such findings reinforce ZOLL’s efforts to incorporate instantaneous CPR support in its products.

“In 2002, ZOLL was the first manufacturer to recognize the importance of helping rescuers with CPR performance,” said Richard A. Packer, President and Chief Executive Officer of ZOLL. “This approach has been validated by the strong emphasis on CPR in the 2005 AHA Guidelines. To date, ZOLL estimates more than 500,000 rescuers worldwide have access to ZOLL AEDs with Real CPR Help that assist them in performing high-quality CPR. We will continue our commitment to offer technology that helps both lay rescuers and healthcare professionals to provide the best possible CPR and improve their resuscitation efforts so that more people survive cardiac arrest.”

SCA is an abrupt disruption of the heart’s function causing lack of blood flow to vital organs, which results in the loss of blood pressure, pulse, and consciousness. In nearly half of all victims, SCA is caused by an abnormal heart rhythm called ventricular fibrillation (VF). VF occurs when the nerves in the heart malfunction, causing the left ventricle (the heart’s main pumping chamber) to quiver or “fibrillate.” Stricken with this chaotic rhythm, the heart cannot effectively pump oxygenated blood to the brain and other vital organs throughout the body.
