Summary

The dyspnea is a common symptom in patients with many respiratory diseases particularly chronic obstructive airway diseases, but also cardiovascular pathologies, obesity, or also in the deconditioned healthy subjects. Called volatolom corresponds to the set of volatile organic compounds (VOCs) contained in exhaled air. The analysis of volatolom can be done either by the methods based on mass spectrometry which allows the identification of each VOC in the exhaled air or by the use of electronic noses which are more simple to use, less specific and produce a quantitive signal change based on pattern recognition algorithms providing a global profile of the VOC without identifying them. The aim of the study is to determine whether the analysis of VOCs in exhaled air would identify biomarkers related to the intensity and type of experimental dyspnea.
