Long-term oxygen therapy

The role of long-term oxygen therapy in the management of patients with hypoxemia is discussed. A brief history of the use of long-term oxygen therapy and its benefits is provided. The actual prescription of long-term oxygen therapy and reimbursement issues are reviewed. The use of long-term oxygen therapy, particularly in the home and for travel is addressed. In recent times, the focus of oxygen therapy delivery has shifted to allow patients receiving repeated oxygen therapy to have increased mobility. Lighter and more portable equipment is now used, and oxygen-conserving devices have been developed that allow the patient's oxygen supply to last longer. An update on this equipment and these devices is provided.
