WebObjective: Forced vital capacity (FVC) and DLCO are used for screening of systemic sclerosis-associated interstitial lung disease (SSc-ILD). The study purpose was to determine the sensitivity, specificity, and negative predictive value (NPV) (proportion of true negative screening tests) of FVC and DLCO thresholds for SSc-ILD on chest high-resolution … WebNormal spirometry & lung volumes: PFT Interpretation – Rapid Guide Methacholine Challenge PC 20 (mg/ml) >16 Normal bronchial response 4-16 Borderline BHR 1-4 Mild BHR <1.0 Moderate-severe BHR PC 20 = provocation concentration at which there is a 20% decrease in FEV 1
