    When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. [10] [11] Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers ...

    The diagnosis of COPD is established through spirometry although other pulmonary function tests can be helpful. A chest X-ray is often ordered to look for hyperinflation and rule out other lung conditions but the lung damage of COPD is not always visible on a chest x-ray. Emphysema, for example, can only be seen on CT scan.

    Bronchospasms can occur for a number of reasons. Lower respiratory tract conditions such as asthma, chronic obstructive pulmonary disease (COPD), and emphysema can result in contraction of the airways. Other causes are side effects of topical decongestants such as oxymetazoline and phenylephrine. Both of these medications activate alpha-1 ...
