Shorter walk test durations to detect ambulatory oxygen desaturation in interstitial lung disease: an observational cohort study
Exertional desaturation manifests during earlier stages of the 6MWT. A 3-min walk has 87-91% sensitivity in detecting oxygen desaturation requiring ambulatory oxygen therapy, while retaining prognostic value. Shorter walk durations can efficiently detect desaturation in ILD, making it more patient-centred and feasible for remote testing.
