Long-term oxygen treatment in chronic obstructive pulmonary disease: recommendations for future research: An NHLBI workshop report

Academic Article

Abstract

  • Long-term oxygen treatment (LTOT) prolongs life in patients with chronic obstructive pulmonary disease (COPD) and severe resting hypoxemia. Although this benefit is proven by clinical trials, scientific research has not provided definitive guidance regarding who should receive LTOT and how it should be delivered. Deficiencies in knowledge and in current research activity related to LTOT are especially striking in comparison to the importance of LTOT in the management of COPD and the associated costs. The National Heart, Lung, and Blood Institute, in collaboration with the Centers for Medicare and Medicaid Services, convened a working group to discuss research on LTOT. Participants in this meeting identified specific areas in which further investigation would likely lead to improvements in the care of patients with COPD or reductions in the cost of their care. The group recommended four clinical trials in subjects with COPD: (1) efficacy of ambulatory O2 supplementation in subjects who experience oxyhemoglobin desaturation during physical activity but are not severely hypoxemic at rest; (2) efficacy of LTOT in subjects with severe COPD and only moderate hypoxemia; (3) efficacy of nocturnal O2 supplementation in subjects whoshow episodic desaturation during sleep that is not attributable to obstructive sleep apnea; and (4) effectiveness of an activitydependent prescription for O2 flow rate that is based on clinical tests performed at rest, during exercise, and during sleep.
