Ambulatory Oxygen Therapy for Individuals With Mild-to-moderate Interstitial Lung Disease
The investigators plan to conduct a study to find out if giving portable oxygen therapy (during physical activity) to patients with interstitial lung disease will improve quality of life, exercise tolerance, shortness of breath, and blood vessel function. Oxygen will be provided for a period of 8 weeks. Additionally, the investigators plan to investigate if it is helpful to deliver individualized support when providing oxygen therapy, through check-in phone calls with a respiratory therapist and by providing additional educational material.
• Individuals with fibrotic ILD (all sub-groups of ILD) who have normal oxygen saturation at rest (SpO2 \> 90%) but develop exertional hypoxemia as demonstrated by a SpO2 = 80-89% with activity (measured during 6MWT).
