May 8, 2009 - Sudden Cardiac Arrest Survival Rates Increase with AutoPulse INVESTOR CONTACT: A.

Prior to installing the devices on its first responder equipment, the department was recording only an 8 percent SCA survival rate. According to Battalion Chief John Davidson, who heads EMS operations, the AutoPulse has been used about 65 times since it went into service last August. Most recently on March 29, it helped save the life of 52-year-old financial analyst David Krogh, who was stricken with SCA while mowing the lawn. A physician’s assistant driving by stopped and began CPR. She continued basic life support until the fire department arrived about three minutes later with the AutoPulse, which administered uninterrupted, automatic chest compressions for two minutes. Krogh was then successfully defibrillated and transported to the hospital. “I’ve been a paramedic for 26 years and have never seen the number of saves we’ve had since using the AutoPulse,” said Davidson. “With Mr. Krogh, it was one of the quickest codes I’ve witnessed in terms of how quickly we were able to get his pulse and respiration back.” “It is difficult for a human provider to replicate the kind of perfusion CVFD has been seeing with the AutoPulse, especially for prolonged periods of time,” Davidson commented. “We’ve observed people who have been down 20 minutes and appear cold and cyanotic, and soon become pink and warm after using the device. AutoPulse is safer for our rescuers since they aren’t standing up in the back of an ambulance doing ineffective CPR. We’ve also eliminated most of the interruptions typically encountered in CPR cases, including during transfers, and going down narrow hallways, stairs, or elevators.” Krogh, who now has an implantable cardioverter defibrillator, says he didn’t remember anything when he woke up in the hospital two days later, which is typical of someone who suffers SCA. Neither he nor his family has a history of cardiac arrest. Medical professionals have been unable to determine why he was stricken with this most often fatal heart failure. As soon as he was well enough, Krogh went back to thank his rescuers at CVFD. He coincidentally is a member of the Chula Vista’s Growth Management Oversight Committee (GMOC), which monitors the city’s fire and emergency response times. “Since GMOC is scheduled to do a top-to-bottom review of its quality of life standards in the coming year, I have a newfound personal insight into the need to update our standards to current best practices, including the acquisition of the new equipment that probably saved my life,” he said. “I’m thankful for the dollars invested on AutoPulse in my city; I want our firefighters to get to emergency scenes fast enough so that other citizens will be as fortunate as I have been.” The AutoPulse Non-invasive Cardiac Support Pump is an automated, portable device with an easy-to-use, load-distributing LifeBand® that squeezes the entire chest, improving blood flow to the heart and brain during sudden cardiac arrest (SCA). The AutoPulse may offer a significant advantage over manual CPR, moving blood more consistently than human providers. AutoPulse delivers high-quality, uninterrupted chest compressions to maintain myocardial and cerebral perfusion. Additionally, it offers the benefit of freeing up rescuers to focus on other life-saving interventions. Over 4,000 AutoPulse devices are in use in hospital and emergency service organizations worldwide. About Sudden Cardiac Arrest SCA, an abrupt disruption of the heart’s function, which causes a lack of blood flow to vital organs, claims more than 325,000 lives each year in the U.S. It is the leading cause of unexpected death in the world and strikes without warning. Currently, only about 5 percent of victims survive; 95 percent will die from SCA.
