Clinical Trial Summary

- Assessment of diaphragmatic function (excursion, thickness variation, thickness ratio) in COPD and bronchial asthma patients. - Assessment of presence of correlation between diaphragmatic dysfunction and pulmonary function. - Assessment of possible association between diaphragmatic dysfunction and presence of reversibility in pulmonary function post bronchodilator.
