Detection of Peripheral Ventilation Inhomogeneity in Smokers

Detection of Peripheral Ventilation Inhomogeneity in Smokers

BACKGROUND: In smokers, ‘small airways’ narrowing alters the conventional, vital capacity single breath washout (SBWVC). Although, in some studies, the test predicts smokers at risk of developing chronic airflow limitation, its wide variability partly explains its poor positive predictive value. An...
