Caring for critically ill patients and their families is a tremendous privilege and responsibility. 

A responsibility because there is nothing more precious to a human being than their child, and a privilege because I consider it an honor to walk along side families during such trying times.  The ICU can be an imposing place to be, with many caregivers to get to know and a sick child.  My goal is to provide expertise, love and support to patients and their families in real time, and also to look for ways to make the care we provide better in the future.

Professional History

Dr. Kheir joined the staff of the Boston Children’s Hospital Heart Center in 2010.  He is a staff physician in the cardiac intensive care unit, where he cares for critically ill patients with congenital heart disease.  He is also the co-founder of the Translational Research Lab within the Heart Center, a group focused upon the development of new diagnostic and treatment tools related to oxygen deprivation, a common problem in patients with severe heart disease.  For example, he and his group are developing tools to deliver oxygen directly to the bloodstream for use in extreme emergencies.  Among his other interests are new ways to determine whether patients are receiving sufficient oxygen delivery following their operations, particularly in infants with hypoplastic left heart syndrome.
