The 15-Step Oximetry Test: a Reliable Tool to Identify Candidates for Lung Transplantation Among Patients With Idiopathic Pulmonary Fibrosis

The lowest saturation and desaturation areas on the 15-step oximetry test are significantly associated with long-term outcome in patients with IPF. We suggest that the 15-step test be used as a simple and reliable tool to predict severity and prognosis in IPF and to identify candidates for lung transplantation.
