Sudden cardiac arrest can strike anyone, anywhere and at any time, often without warning. Reported survival rates for cardiac arrest with ventricular fibrillation are low: from 3 to 10 percent. Studies have shown that rapid defibrillation after out-of-hospital cardiac arrest with ventricular fibrillation is the most important determinant of survival. That is why training people to use automated external defibrillators, or AEDs, in public places can double the odds that a person in cardiac arrest will survive. The ADA recently awarded the Seal of Acceptance to HeartStart OnSite and FR2+ defibrillators. HeartStart defibrillators are easy to use. HeartStart defibrillators are designed specifically for the lay responder. They provide clear, easy-to-follow voice instructions and a simple user interface to guide the responder through an emergency reliable. HeartStart defibrillators perform comprehensive daily, weekly and monthly self-tests to help ensure readiness. A highly visible status indicator shows at a glance that the device is ready for use safe. HeartStart defibrillators have an innovative design that makes it virtually impossible to shock someone who is not in cardiac arrest. The heart rhythm first is analyzed to ensure that a shock is needed. The device will not allow the user to deliver a shock that the analysis determines is unnecessary. Philips offers two defibrillator models for the dental office: the HeartStart OnSite Defibrillator and the HeartStart FR2+ Defibrillator. The HeartStart OnSite Defibrillator is intended to be easy to use for responders in an office setting. It provides step-by-step verbal instructions on how to perform cardiopulmonary resuscitation, or CPR. The HeartStart FR2+ Defibrillator is designed for first responders, such as flight attendants, nurses, police officers and designated workplace responders who participate in regular training. Each HeartStart defibrillator comes with a nonrechargeable long-life battery, two sets of adult pads and complete instructions for use.
