Usefulness of the culturally adapted oxygen-cost diagram in the assessment of dyspnea in Puerto Rico.

Objective: Breathlessness is a common and disabling symptom of pulmonary disease. Measuring its severity is recommended as such measurements can be helpful in both clinical and research settings. The oxygen-cost diagram (OCD) and the Medical Research Council (MRC) dyspnea scale were developed in English to measure severity of dyspnea.
