This study is looking at people who experience shortness of breath (dyspnea) and are having a Cardiopulmonary Exercise Test (a test that checks your heart and lung function during exercise). Researchers want to see if a device called the tremoFlo C-100 Airwave Oscillometry System, which measures how much resistance there is in your airways, is connected to any unusual findings from your exercise test. They will measure the average resistance and reactance (a measure of how much your airways resist airflow) using the Oscillometer. You can join if you are 18 or older, can speak English, and are willing to do a breathing test. The study aims to enroll 50 participants, but its current recruitment status is unclear.

Study design

This is an observational study involving 50 participants. It is not a treatment study, but rather looks at the relationship between different measurements.

What's involved

You will need to perform a breathing test using the Oscillometer. This will be a single measurement, likely on one day.

Compensation

Not stated in the trial record.

Follow-up
