The 2020 American Heart Association (AHA) Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care – Heart & Stroke Edition provides a comprehensive review of evidence-based recommendations for resuscitation and emergency cardiovascular care.
 
The approach for this 2020 guidelines document reflects alignment with the International Liaison Committee on Resuscitation (ILCOR) and associated member councils and includes varying levels of evidence reviews specific to the scientific questions considered of greatest clinical significance and new evidence.

The 2020 Guidelines contain 491 recommendations and are organized into knowledge chunks, grouped into discrete modules of information on specific topics or management issues. Each modular knowledge chunk includes a table of recommendations, a brief introduction or synopsis, recommendation-specific supportive text, hyperlinked references, and, when relevant, figures, flow diagrams of algorithms, and additional tables.
