Long term oxygen therapy (LTOT) for patients with hypoxic chronic bronchitis and emphysema is critically important; it has been shown to positively impact longevity and reduces repeat hospital admission rates. Correspondingly, the technical performance of each device is of great import. In this missive, the authors purport to evaluate the FIO2 levels of home oxygen concentrators at various flow rates from two to five liters per minute. The accuracy of the oxygen concentrator, as compared to the manufacturer's claims, was determined.
