Alveolar-capillary Reserve After Exercise in Chronic Obstructive Pulmonary Disease (COPD) (COP-DTPA)
Alveolar-capillary Reserve After Exercise in COPD
Source: ClinicalTrials.gov · Last updated 8 Dec 2025
Brief summary (registry, in English)
It is unknown whether individuals with COPD exhibit abnormal alveolar-capillary breaching during exercise, and whether this contributes to exertional dyspnoea. The aim of this study is to investigate whether individuals with COPD exhibit an abnormal increase in alveolar-capillary breaching during exertion, as indicated by an increase alveolar-capillary permeability with a concomitantly exacerbated increase in lung tissue mass.
