Researchers at The University of British Columbia (UBC) are recruiting participants for a clinical trial designed to assess the sensation of shortness of breath (dyspnea) in patients with cystic fibrosis (CF) during exercise.

The primary goal of the trial is to assess whether dyspnea is qualitatively and quantitatively different between CF patients and healthy controls during exercise.

The hypothesis proposed by UCB researchers is that a reduced tidal volume response in CF patients during exercise will generate different assessments (or qualitative descriptors) regarding exertional dyspnea compared to healthy individuals of similar age and sex.
