ZOLL’s patented See-Thru CPR helps minimize interruptions in CPR—one of the key recommendations of the American Heart Association’s (AHA) Guidelines for Advanced Cardiac Life Support. See-Thru CPR reduces interruptions by allowing clinicians to see organized electrical activity during CPR compressions by filtering out compression artifact (“noise”). This lets rescuers see a patient’s underlying cardiac rhythm during resuscitation efforts and eliminates the need to stop compressions to see if defibrillation was successful. The AHA notes that a primary source of interruption of CPR is stopping to determine underlying ECG rhythm. “This exclusive ZOLL technology allows the professional rescuer to analyze a patient’s heart rhythm while continuous CPR is in progress and monitor the heart rhythm to determine the appropriate time to analyze or stop CPR to check the ECG,” said Richard A. Packer, President and Chief Executive Officer of ZOLL. “It contributes to helping rescuers and clinicians save more lives.” Manual Mode Only See-Thru CPR will only be activated when the AED Pro is in Manual Mode. The feature will not be enabled when the AED Pro is operating in semi-automatic mode. See-Thru CPR will automatically “turn on” when the rescuer switches the unit from semi-automatic to manual, which is accomplished by depressing two soft keys. AED Pro: Advanced Capabilities, Rugged Construction The AED Pro is the first defibrillator designed for professional responders with instantaneous feedback on CPR chest compressions. Its unique real-time feedback, Real CPR Help™, includes a metronome set at the AHA-recommended 100 beats per minute and a screen display, which helps rescuers achieve the optimum rate and depth of compression levels through audible and/or visual prompts. All CPR data can be recorded and reviewed using RescueNet™ Code Review software. It also features a high-resolution ECG display, Lead II monitoring, and unrivaled battery compatibility. Its rugged construction and exceptional durability support the needs of both Basic Life Support and Advanced Life Support professionals in hospitals and emergency services. Sudden Cardiac Arrest: World’s Leading Cause of Unexpected Death Sudden cardiac arrest (SCA) is an abrupt disruption of the heart’s function, which causes a lack of blood flow to vital organs. This lack of blood flow can result in the loss of blood pressure, pulse, and consciousness. SCA is the leading cause of unexpected death in the world and strikes without warning. In the U.S. alone, there are more than 325,000 deaths each year from cardiac arrest. Currently, only about 6 percent of victims survive.
