In routine clinical practice, exercise SpO2 is usually measured at the finger; however, the finger reading can be unreliable in some patients, and there is currently no recommendation on the best sensor location in ILD. This study compares the two sensor locations, recorded at the same time, and evaluates whether any disagreement changes how exercise desaturation is classified and whether ambulatory oxygen is indicated.\n\nAll patients undergoing a 6MWT as part of routine ILD care are included consecutively to ensure a pragmatic, real-world representation of the ILD population. The primary objective is to measure the agreement between the two locations in the lowest SpO2 reached during the test, including the size and direction of any difference. Secondary objectives include the reclassification of patients at the clinical desaturation thresholds, the comparison between autoimmune and non-autoimmune ILD, the rate of invalid readings at each location, and the clinical, vascular and functional factors associated with disagreement.",[62,63,64,65,66],"Interstitial Lung Disease (ILD)","Idiopathic Pulmonary Fibrosis (IPF)","Progressive Pulmonary Fibrosis","Connective Tissue Disease-Associated Interstitial Lung Disease","Interstitial Lung Disease Due to Connective Tissue Disease (Disorder)",[68,69,70,71,72,73,74,75,76,77,78,79,80,81],"Pulse Oximetry","Earlobe Oximetry","Finger Oximetry","Oxygen Saturation","SpO2","Six-Minute Walk Test","Exercise Desaturation","Ambulatory Oxygen","Interstitial Lung Disease","Idiopathic Pulmonary Fibrosis","Connective Tissue Disease-ILD","Systemic Sclerosis","Method Comparison","Bland-Altman Analysis","2026-07-21",{"date":84,"type":85},"2026-07-23","ACTUAL",{"date":87,"type":85},"2026-01-13",{"date":89,"type":58},"2027-12-31",{"name":5,"class":6},1]
