Prior studies have reported that supplemental oxygen can confer acute benefits to cognition. Here, the investigators seek to replicate/extend such findings by assessing whether such benefits can be seen using an Inogen oxygen concentrator with subjects with an average age around 65 years old. The investigators include a standard measure of cognition previously reported to be sensitive to supplemental oxygen (2-back test) and a novel, in-development adaptation of a memory test for medical-related content (Medical icons spatial test).
