FOR IMMEDIATE RELEASE

ZOLL Launches AHA/ERC Guidelines-Compliant M Series
All ZOLL Defibrillators Now Compliant  

November 14, 2006—CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and related software solutions, today announced it is now shipping all models of the ZOLL M Series® defibrillator that comply with 2005 AHA/ERC Guidelines. With this change to the M Series, ZOLL’s entire line of defibrillators now complies with updated Guidelines. The M Series and other resuscitation products are in ZOLL’s booth (#1589) at the 2006 Scientific Sessions of the American Heart Association in Chicago taking place through November 15, 2006.

To treat cardiac arrest, the 2005 Guidelines now recommend delivery of a single shock followed immediately by a period of CPR, beginning with chest compressions (Class IIa). This replaces the old recommendation of a “stacked” sequence of up to 3 shocks without interposed chest compressions. This version of the M Series now accommodates this new recommendation when in AED and Advisory modes, allowing for longer periods of uninterrupted chest compressions. 

Along with the compliant M Series, AHA Scientific Sessions attendees will have an opportunity to test their CPR skills, which involves performing two minutes of CPR using a 2005 AHA/ERC Guidelines-compliant ZOLL AED Plus™ and ZOLL AED Pro® defibrillators. After an attendee completes two minutes of CPR, data will be immediately downloaded wirelessly (via an infrared port on the side of the AED) and evaluated on ZOLL CodeNet® software in real time so attendees can see for themselves the following information:

  • The complete ECG that acts as a timeline for the entire rescue event;
  • A readout of the frequency and depth of their CPR chest compressions;
  • Percentage of  “Compressions in Target”;
  • A visual representation of all compressions in terms of depth and rate; and
  • Data points showing when audible prompts (e.g., “Push Harder” or “Good Compressions”) were communicated to the rescuer.

ZOLL personnel will evaluate CPR performance by measuring “Compressions In Target.” When a chest compression is done at the proper rate (i.e., between 80 to 110 compressions per minute) and the proper depth (i.e., 1 ½ to 2 inches), that compression is considered “in target,” meaning that it is effective in helping maintain blood flow to the brain and heart of a patient in cardiac arrest.

In addition to the “CPR Challenge,” ZOLL will feature the following resuscitation products. 

  • The R Series: First and Only “Code-Ready” Defibrillator for Hospitals
    The R Series™ is a defibrillator that sets a new standard for simplicity and operational readiness, which will help improve in-hospital resuscitation efforts. (see press release entitled “ZOLL Launches First and Only ‘Code-Ready™’ Defibrillator for Hospitals: R Series” distributed on November 10, 2006).
  • ZOLL CodeNet
    CodeNet is the only comprehensive system for hospital code response teams to document, manage, and review cardiac arrest event and resuscitation data. It provides efficiencies in data capture and reporting. CodeNet time stamps logged events and synchronizes these times with defibrillator data, providing clinicians with a complete and accurate timeline of an entire cardiac arrest event.
  • AED Plus and AED Pro Automated External Defibrillators
    The AED Plus™ and AED Pro® offer Real CPR Help™ through the use a special electrode, known as the CPR-D•padz™, which includes a sensor that measures the rate and depth of chest compressions. This Real CPR Help functionality offers rescuers instantaneous feedback on the rate and depth of chest compressions. In addition, the AED Pro supports the AHA recommendations of a universal compression-to-ventilation ratio of 30:2 for single rescuers. The AED Pro also includes configurable options so the device can be used by either first responders or clinicians.
  • AutoPulse Non-invasive Cardiac Support Pump
    The AutoPulse®—the only device of its kind—delivers the consistent, uninterrupted chest compressions that the 2005 AHA/ERC Guidelines call for. The Guidelines note that load-distributing band CPR “may be considered for use by trained personnel as an adjunct to CPR for patients in cardiac arrest (Class IIb).”* It 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 cardiac arrest.* Additionally, it can help free up rescuers to focus on other life-saving interventions. Recent study results demonstrate that the AutoPulse has contributed to improvements in long-term and short-term survival rates.*
  • LifeVest Wearable External Defibrillator
    The LifeVest® wearable defibrillator is worn by patients at risk for sudden cardiac arrest. To date, more than 3,700 patients have worn the LifeVest, resulting in more than 75 life-saving events. The LifeVest monitors the patient’s heart continuously, and if the patient goes into a life-threatening heart rhythm, the device delivers a shock treatment to restore the patient’s heart to a normal rhythm.
