Safe cardiopulmonary bypass is critical to the success of a cardiac surgical program. Dr. Jonas maintains active laboratory and clinical research programs. He has spent his career studying ways to improve the safety of cardiopulmonary bypass, particularly as it relates to neurological development. His development of a clinical research program in cardiopulmonary bypass techniques has revolutionized the field of pediatric cardiac surgery. Using safer strategies for bypass has resulted in improved outcomes, quicker intensive care unit recovery, shorter lengths-of-stay, fewer neurological injuries, and better long-term neurodevelopmental outcomes. Dr. Jonas continues to study advanced bypass techniques within the Children’s National Heart Institute in a dedicated research laboratory. He also has authored more than 300 peer-reviewed manuscripts.
