Provided as a public service by Mickey S. Eisenberg, M.D., a Professor of Medicine at the University of Washington, this site offers a basic guide to Cardiopulmonary Resuscitation (CPR). The core of the site is the CPR Info section, which contains instructions for Quick and Standard CPR, and performing CPR on children and infants. From this section, users can print out a basic illustrated pocket guide to CPR. Other resources include guides to first aid for choking, CPR facts and history, a Quicktime video demonstration, a quiz, related links, and an Ask the Doctor section, which invites questions and prints answers to previous queries. While Doctor Eisenberg notes that "CPR started by a bystander doubles the likelihood of survival for victims of cardiac arrest," he also cautions that the site should serve as an introduction and basic guide, not a substitute for real CPR training.
