-
Many persons with lung disease require the use of supplemental low-flow oxygen, which has been shown to reduce the physiological effects of hypoxemia, increase exercise tolerance, and improve t he user's sense of well-being. This article discusses three systems used for long-term delivery of oxygen, the financial considerations of these systems, and developments in the new technology of oxygen-conserving devices, which may decrease oxygen consumption and costs while providing increased comfort and mobility for users.
