Cardiopulmonary Exercise Testing and Oscillometry for the Evaluation of Dyspnea

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.

Must be able to speak and understand English
Referred for Cardiopulmonary Exercise Testing

Exclusion criteria

Unable to provide consent or perform oscillometry test

Treatment and study plan

Oscillometer

Device

The tremoFlo C-100 Airwave Oscillometry System is intended to measure respiratory system impedance using the Forced Oscillation Technique (FOT).

Other names: THORASYS tremoFlo C-100 Airwave Oscillometry System

Primary outcomes

Mean respiratory system resistance and reactance

Time frame: Single measurement, approximately day 1

The oscillometer will collect an airway impedance measurement which is made up of multiple variables.
