Supplemental Oxygen in Pulmonary Fibrosis

The investigators aim to recruit patients with PF to participate in interviews and/or a one-year study of supplemental oxygen (O2). In the one-year study, the investigators will collect data before and for one year after PF patients are prescribed daily-use supplemental oxygen and compare outcomes, including shortness of breath, quality of life, fatigue, cough, and day-to-day functioning before and after O2.
