Home oxygen therapy.

ABSTRACT

Home oxygen therapy has well-established benefits for patients with chronic obstructive pulmonary disease and resting hypoxemia. The indications for therapy have been clearly defined in the United States by the Health Care Financing Administration (HCFA), and these guidelines have been accepted by most third-party payers. Controversies regarding the use of oxygen during sleep and exercise when daytime hypoxemia is not present have important therapeutic and financial implications. HCFA has recently proposed a substantial reduction in reimbursement for home oxygen which could have a major adverse effect if done on a global, across-the-board, basis. Some of the new technological developments in oxygen delivery systems are presented in this article.
