Abnormal Exertional Breathlessness on Cardiopulmonary Cycle Exercise Testing in Relation to Self-Reported and Physiologic Responses in Chronic Airflow Limitation
Background: Exertional breathlessness is a cardinal symptom of cardiorespiratory disease. Research Question: How does breathlessness abnormality, graded using normative reference equations during cardiopulmonary exercise testing (CPET), relate to self-reported and physiologic responses in people with chronic airflow limitation (CAL)? Study Design and Methods: An analysis was done of people aged ≥
