Reference values for Lung Clearance Index (LCI) derived from sulphur hexafluoride multiple breath washout testing

Published: 10 November 2020

A new study was published on ERS (European Respiratory Society) Journal to provide LCI (Lung Clearance Index) reference values in pulmonary healthy adults.

Lung clearance index (LCI) is the most commonly used MBW outcome parameter but normative data is scarce.

LCI was derived from triplicate MBW measurements based on Sulphur hexafluoride (SF6) and no influence of height, weight and gender was seen.

Reference values can now be provided over the whole age range and for two different stopping points.
