Chronic obstructive pulmonary disease: Difference between revisions

Line 1:

'''Chronic obstructive pulmonary disease''' (COPD) is characterised by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities. It’s common, preventable, and treatable. It is defined as a post-bronchodilator [[FEV1/FVC ratio]] of < 0,70.

It’s common, preventable, and treatable. It is defined as a post-bronchodilator [[FEV1/FVC ratio]] of < 0,70.

It affects 11,7% of the world and it’s the third leading cause of death worldwide. Prevalence is expected to rise, and it’s expected to be the leading cause of death in 15 years.

COPD has two phenotypes, '''chronic bronchitis''' and '''emphysema'''.

COPD is a chronic disease with periodic [[COPD exacerbations|flare-ups or exacerbations]], during which more intensive therapy is needed.

Line 50:

The bronchodilator test is performed to distinguish COPD from bronchial asthma. If the FEV1 improves more than 12% after bronchodilator, bronchial asthma is diagnosed.

=== Imaging ===

Imaging is not necessary for the diagnosis of COPD. In case of emphysema, [[chest radiography]] will show hyperinflation of the lungs, as evidenced by horizontal ribs, widened intercostal space, increased anterioposterior diameter (seen on the lateral view), flattened diaphragm, and increased transparency of the lung.<section end="radiology" />

Differential diagnosis:

=== Differential diagnosis ===

* Bronchial [[asthma]]

* [[Lung cancer]]

Line 104:

Line 106:

** [[Pneumothorax]] (due to rupture of bullae)

** Weight loss, [[cachexia]]
