Trans Thoracic Ultrasound to Assess Diaphragmatic Function in Stable COPD Versus Bronchial Asthma.

Trans Thoracic Ultrasound to Assess Diaphragmatic Function in Stable COPD Versus Bronchial Asthma.

• 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)

Inclusion Criteria:

Stable patients (not in exacerbation).

Exclusion Criteria:

• Patients with comorbidities as cardiac, renal or hepatic diseases.
• Patients who have combined COPD and bronchial asthma.
