Oxygen desaturation during walk test at diagnosis linked to earlier lung function decline in fibrotic ILD
ERS publications reported that a fall of at least six percentage points in SpO2 during the 6MWT at diagnosis predicted earlier FVC decline and worse transplant-free survival.

A change in blood oxygen saturation during the six-minute walk test (6MWT) at diagnosis was linked to later outcomes in fibrotic interstitial lung disease (ILD), according to a post from ERS publications on X.
The post said that a change in SpO2 of −6 percentage points or more during the 6MWT at diagnosis "consistently predicted" an earlier decline in forced vital capacity (FVC) of at least 5 percentage points. It also predicted worse transplant-free survival.
The post added that combining this measure with FVC and six-minute walk distance (6MWD) helps identify low-risk patients and supports earlier risk stratification.
The post did not name the journal, the authors, the size or design of the study, or the patient groups included. It linked to further material that was not available in the source text.
ERS publications is the account for the European Respiratory Society's journals and books, including the European Respiratory Journal and ERJ Open Research.
