What parameters define ILD severity?

ILD severity is assessed using FVC %predicted, DLCO %predicted, 6-minute walk distance, CT extent of fibrosis, and presence of honeycombing. FVC <70% and DLCO <40% indicate advanced physiological impairment.

When does ILD severity trigger transplant referral?

IPF/ILD patients should be referred for lung transplant assessment when FVC <80%, DLCO <40%, decline in FVC ≥10% over 6 months, decline in DLCO ≥15% over 6 months, or oxygen desaturation on 6MWT.
