The Future of Ambulatory Oxygen
Thomas L. Petty, MD, FAARC University of Colorado Health Science Center, Denver, Colorado
Ambulatory oxygen has become the standard of care for patients who will and can ambulate beyond the 50-foot tubing which is connected to a stationary system. Ambulatory oxygen probably improves bioenergetics at the tissue level by improving tissue oxygen transport.
Newer, lightweight portable oxygen systems are making ambulation with oxygen even more attractive and less burdensome than ever before. Home transfilling oxygen systems using both gaseous and liquid technologies are being introduced. Ambulatory oxygen may have applications beyond the hypoxemic state. This may benefit patients with severe dyspnea on exertion, who are not hypoxemic, and patients who are limited by dyspnea due to severe obesity, but who do not have profound exercise hypoxemia.
