Research Interests

At the Boise VA Medical Center, we use a sheep model to study the bronchial circulation, hemodynamic alterations in septic shock, and pleural space infection. Specifically, our studies have addressed bronchial arterial receptors and nitrergic control, response to bronchodilators, and the changes in bronchial blood flow in response to lung injury. We have completed a series of studies on the hemodynamic response to non-ionic contrast in a model of occluded versus open pulmonary vasculature, and are currently in the process of starting a series of studies addressing airway mechanics and bronchial blood flow in response to ErBY cautery and airway heating.
