About this study

The purpose of this study is to obtain breath acoustic recordings and measures of lung mechanics in patients with COPD, asthma, and cystic fibrosis breathing at rest and during light submaximal exercise. The plan is to examine these respiratory acoustics and mechanics in relation to determinants of disease and/or disease states (classic respiratory pathophysiology) and quality of life measures in these patient populations to determine if any relationship or patterns exist when comparing across respiratory diseases and within a condition based on disease severity.       

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
