Finger vs. Earlobe Pulse Oximetry During a 6-Minute Walk Test in ILD
Official title: A Prospective, Multicenter, Observational Method-Comparison Study of Finger Versus Earlobe Pulse Oximetry for Oxygen Saturation During the Six-Minute Walk Test in Patients With Interstitial Lung Disease (OXISITE-ILD)
Run by Hospital de Granollers · NCT07723872 · Data updated 2026-11-12
This study tests whether finger or earlobe pulse oximetry gives the same oxygen saturation readings during a 6-minute walk in people with interstitial lung disease.

Is this trial a fit for you?
✓Likely a good fit
Adults with confirmed ILD who can perform a 6MWT and have reliable baseline readings on both finger and earlobe oximetry.
✕Probably not a fit
Patients with ILD who cannot obtain valid simultaneous readings from both sites or have conditions affecting sensor accuracy may not benefit.

What this trial studies
OXISITE-ILD is a prospective, multicenter, observational study that compares two sensor locations for measuring SpO2 during the 6-minute walk test in ILD patients. Readings are taken at finger and earlobe simultaneously at eight timepoints to determine agreement and see if sensor location would change whether ambulatory oxygen is indicated. The study aims to reflect real-world ILD care by including consecutive patients undergoing routine 6MWT and may include arterial blood gas or capillaroscopy in some participants for interpretation. Each participant contributes a single cross-sectional data set, with at least 100 participants planned at the coordinating center and additional centers as needed. The primary objective is the level of agreement between finger and earlobe SpO2 readings at their lowest values during the test.
Why it matters
Potential benefit: If finger and earlobe readings agree well, clinicians can rely on either sensor location during 6MWT to guide oxygen treatment decisions in ILD.
How similar studies have gone: Prior work in pulse oximetry sensor placement suggests variable agreement across sites, making this cross-site comparison important but not yet universally established in ILD.

Inclusion Criteria: * Adults aged 18 years or older * Confirmed diagnosis of interstitial lung disease (ILD) based on clinical, radiological and/or histological criteria * Newly diagnosed or under follow-up for ILD * Physically and cognitively able to perform the 6-minute walk test (6MWT) * Signed informed consent Exclusion Criteria: * Inability to obtain a reliable, stable baseline pulse oximetry reading at the finger and/or the earlobe, preventing a valid paired baseline measurement and the calculation of agreement * ILD exacerbation, decompensated comorbidity, or acute respiratory infection at the time of the test
