WebFor RV%TLC ratio, the AOC=0.77, sensitivity=77.3 (95%CI - 75.8 to 78.71) and specificity=53.6 (95%CI 51.9 to 55.3). Conclusion: The FRC%TLC is raised in 7% of patients without airflow obstruction, as is the RV%TLC. The worse the airflow obstruction, the greater the ratio observed. WebThe measure that could be estimated with the highest reliability was the ratio RV/TLC, an indicator of air trapping highly correlated with hyperinflation in COPD [ 6, 28 ]. FEV 1 % pred and FVC % pred were sufficient for this prediction, while the effect of anthropometric characteristics was minor, except for the difference between sexes.
