An AED program consists of a design and supporting set of policies and practices that ready an organization for Sudden Cardiac Arrest (SCA) emergencies, suggest what actions should be taken if SCA is encountered and help manage the legal risks that come with owning AEDs. Industry standards and AED laws guide what to include in an AED program’s policies and practices.

Background Experience: For over 25 years, Mr. Lazar has designed and documented AED programs for AED programs nationwide. Examples include Microsoft, the Federal Aviation Administration, 24 Hour Fitness among many others. Earlier in his career, he practiced emergency medical services law, designed emergency medical services (EMS) systems, served as an EMS system administrator, and was an emergency medical technician. He also holds a law degree from Lewis & Clark School of Law and a Bachelor of Science degree in Public Affairs from the University of Oregon.

Mr. Lazar develops and publishes national AED Program Design Guidelines that describe industry standards for AED programs and the AED Law Center, the only comprehensive online information resource that helps AED owners learn about the AED laws for every state, understand the AED laws in plain English, and stay informed about pending AED legislation nationwide.

Litigation Support: As the leader in his industry, Mr. Lazar has provided both consulting and testifying expert services to lawyers in a variety of cases around the U.S. involving sudden cardiac arrest response in workplace and community (non-medical) settings. His deep understanding of AED programs has led him to testify before the U.S. Congress in support of the Cardiac Arrest Survival Act, the FDA on AED over-the-counter and reclassification issues, and numerous state legislatures on AED public policy issues and immunity laws.
