Diaphragm
Conditions
Brief 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.
Detailed description
* 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)
Interventions
5\. Transthoracic ultrasound for both right and left diaphragm during inspiration and expiration.
