The Clinical Exercise & Respiratory Physiology Laboratory is currently focused on identifying new therapeutic strategies for the management of breathlessness and activity-limitation in patients with Chronic Obstructive Pulmonary Disease (COPD). We are looking for COPD patients who would be interested in participating in our research. Willing and eligible participants would be required to visit the Montreal Chest Institute on three or four separate occasions to perform simple lung function tests and an exercise test on a stationary bicycle. Participants will be financially compensated for study related expenses. For more information, go here.
