Résumé

Unexplained dyspnea presents a significant diagnostic challenge. Dyspnea arises when inspiratory neural drive (IND) to the respiratory muscles is increased and the respiratory system fails to meet this increased demand. Cardiopulmonary exercise testing (CPET) is a valuable tool to unravel the causes of exertional dyspnea in the individual. Moreover, analysis of breathing pattern, operating lung volumes and flow-volume loops allows characterization of abnormal dynamic mechanical response to increased IND - an important source of breathing discomfort. We illustrate the clinical utility of this approach which examines respiratory sensation, ventilatory control, respiratory mechanics and cardio-circulatory responses in cases of unexplained dyspnea.
