For the past 15 years Dr Vieillard-Baron has worked as a fulltime intensivist in the medical-surgical intensive care unit at Hospital Ambroise-Pare in Boulogne, France where he has been Director since 2009. He was appointed as professor of critical care medicine in 2003. His academic background includes a PhD with research on the role of matrix metalloproteinases in pulmonary vascular remodeling in models of pulmonary hypertension related to hypoxia and monocrotalline.
He is well known for his research on cardiopulmonary interactions, ARDS, and mechanical ventilation. He has been a pioneer in using transesophageal echocardiography to elucidate the pathophysiology of adverse effects of ventilatory support on hemodynamic function. In addition, he has defined the utility of transesophageal echocardiography (TEE) as a primary clinical tool for hemodynamic monitoring of the critically ill patient.
