New GOLD guidelines recommend using pre-bronchodilator spirometry to rule out COPD and post-bronchodilator measurements to ...

Considerable controversy exists on the best methods to diagnose airflow obstruction. Most of the discrete ratio thresholds used to define airflow obstruction are insensitive to early and mild disease.

This classification is relatively inaccurate, as airflow obstruction in COPD usually occurs in the small airways. Recent studies are, however, illustrating that three different mechanisms of ...

The clinical features of constrictive bronchiolitis consist of a chest radiograph that is often normal, early inspiratory crackles and irreversible airflow obstruction by pulmonary function testing.

General Manager at Sanofi UK and Ireland, Rippon Ubhi, and Jim Shannon MP discuss the burden of chronic obstructive pulmonary ...
