Overview

* 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.

* 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 (FEV1/FVC). * Assessment of possible association between diaphragmatic dysfunction and presence of reversibility in pulmonary function post bronchodilator (short acting B2 agonist)
