Objective: Compare the performance of the OxyArm to that of nasal cannulae in the delivery of supplemental oxygen to patients with chronic obstructive pulmonary disease.

Methods: We tested various oxygen flows with 10 chronic obstructive pulmonary disease patients who were receiving prescribed supplemental oxygen. Blood oxygen saturation (measured via pulse oximetry [S(pO2)]), was measured with each device, and mean data were compared with paired, 2-sample tests.
