Recruiting

• Conditions: Breathing, Mouth; Dyspnea; Lung Function Decreased; Shortness of Breath
• Interventions: Device: Oscillometer

• Registration Number: NCT06554353
• Lead Sponsor: University of Rochester

Brief Summary

This study will determine if airway resistance to airflow and pressure, measured by Oscillometry, is associated with abnormal findings on Cardiopulmonary Exercise Testing in subjects who are experiencing shortness of breath.
