Study of diffusion capacity of lung for carbon monoxide (DLCO) in chronic obstructive pulmonary disease
Journal Title: Medpulse International Journal of Medicine - Year 2019, Vol 9, Issue 3
Abstract
Background: The most useful test of the gas exchange capacity of the lung that correlates with the total functioning surface area of alveolar capillary interface is the DLCO. Aims and Objectives: To Study Diffusing Capacity of Lung for Carbon Monoxide (DLCO) in Patients with COPD. Material and Methods: A study was done with 115 patients in the Department of Respiratory Medicine in a tertiary care centre. Results: Majority of the patients (39.9%) were in the age group of 61-70 years with male pre-ponderance(71.3%). It was observed that 50.4% patients had COPD Gold Grade III followed by 26.1% patients were COPD Gold Grade II, 20.9% patients with COPD Gold Grade IV and 2.6% with COPD Gold Grade I. Majority of the patients (18.8%) had ≥20 pack-year history and DLCO 40-60%. Conclusion: We concluded that as the COPD severity advances there was significant decline in DLco.
