Expiratory dyspnea

Expiratory dyspnea is a subjective feeling of difficulty exhaling. In pediatrics, this is an objectified symptom. This is mainly a prolonged exhalation.

Expiratory dyspnea occurs especially with obstruction of the intrathoracic airways. With moderate obstruction, there is a decrease in respiratory rate, an increase in tidal volume and a slight prolongation of expiration. In case of severe obstruction, there is an increase in respiratory rate, involvement of auxiliary respiratory muscles (retraction of the jugular, intercostals, and hypochondrium) and significant prolongation of expiration. Causes:
 * bronchial asthma;
 * emphysema;
 * COPD.
