Brief Biography

Dr. Kavanagh graduated from University College Dublin (Ireland) in 1985. Following residency in Internal Medicine in Dublin and in Anaesthesia (residency and fellowship) in Toronto, he trained in Critical Care Medicine in Stanford. He returned to the Toronto General Hospital in 1994 and in 1999 moved to the Hospital for Sick Children where he is a clinician-scientist and holds the Dr. Geoffrey Barker Chair in Critical Care Medicine. His laboratory investigates mechanisms of ventilator-induced lung injury and the actions of carbon dioxide in the lung. Dr. Kavanagh is the chair of Critical Care Canada Forum; he is an associate editor (Critical Care) and an executive editor (Anesthesiology). In 2017 he completed two terms as Chair, Department of Anesthesia, University of Toronto.

Research Interests

• Mechanical ventilation

• Critical care medicine

Research Activities

My laboratory has been investigating the effects and mechanisms of lung damage associated with mechanical ventilation.

We have found that adverse ventilatory strategy may permit the release of bacterial products from the lungs into the blood stream, and that increased levels of carbon dioxide may be protective against lung damage and systemic organ injury.

These findings are potentially applicable to critically ill patients on life support devices in Intensive Care Units.
