Background: This preliminary study to measure lung volume in patients with stable COPD in Persahabatan Central General Hospital Jakarta to determine the prevalence of the increasing value of lung volume in patients with stable COPD.Methods: This study used a cross-sectional study design of outpatients with stable COPD who visited the asthma-COPD clinic at Persahabatan Central General Hospital Jakarta. The Lung volume test using a gas dilution Multiple Breath Nitrogen Washout (MBNW) was taken consecutively from February to March 2016.Results: Tests of spirometry and Lung volumes were performed on 35 subjects. There were 3 subjects (8.6%) in COPD Group A, 9 subjects (25.7%) in COPD Group B, 9 subjects (25.7%) in COPD Group C, and 14 subjects (40%) in COPD Group D. At the age of 60 years, there were subjects (25.7%) and 60 years, 26 subjects (74.6%). Value Residual Volume/Total Lung Capacity (RV/TLC) has a significant relationship with the symptoms and a 6-minute walking test; however, Functional Residual Capacity/Total Lung Capacity (FRC/TLC) is significantly associated with the symptoms, a 6-minute walking test, and exacerbations within one year.Conclusion: Value RV/TLC has a significant relationship with the symptoms and a 6-minute walking test; however, FRC/TLC is significantly associated with the symptoms, a 6-minute walking test, and exacerbations within one year.
