Clinical trials: Breath-holding Spell
Healthy Subjects
Analysis of Breath Volatile Organic Compounds After Dyspnea Induced in the Healthy Subject.
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.
