This course will focus on the approach to interpreting pulmonary function and cardiopulmonary exercise tests, moving from the basic physiologic underpinnings to implementation in clinical practice. We will combine didactic lectures with case-based instruction in small group settings, and we will offer participants the opportunity to bring their own complex cases for review by an expert team of clinicians and physiologists. Small group discussion will include pulmonary function and exercise tests, and we will use a team approach to facilitating the group discussions including content experts and pulmonary function laboratory medical directors from around the world.
