Research Interests

My research centers around the study of lung mechanics in health and disease and at rest and during exercise. Currently, we are studying the effects of breathing hyperoxic helium gas on dynamic hyperinflation and the work of breathing in exercising COPD patients. Other studies being done during 2003 include a relatively invasive study to determine if intrapulmonary shunting is important as a cause for exercise-induced hypoxemia in athletes. For this study we will be inserting a catheter into the pulmonary artery and radial artery and then injecting agitated saline while performing transthoracic echo during exercise to quantitate shunt.

Another series of studies will determine the effects on lung mechanics of combining high frequency chest wall oscillation with oral high frequency oscillation and on the effects of positive expired pressure during high frequency chest wall oscillation. These studies will be done in patients with cystic fibrosis and patients with COPD. Also, we are in the final stages of a long study of the effects of a rehabilitation exercise program on leg muscle oxygenation, pain perception and quality of life in patients with peripheral vascular disease.
