Question

Quizplus · Accepted Answer

The stages of COPD can be assessed by all of the above except chest x-ray. Functional dyspnea, body mass index, and spirometry are used to assess the different stages of COPD. The spirometry helps in measuring the ratio of forced expiratory volume in the
first second of expiration after complete inhalation to total forced vital capacity. The chest x-ray has no role in defining the stages of COPD.
