Long-term oxygen treatment does not benefit some COPD patients
Newly published data from the Long-Term Oxygen Treatment Trial (LOTT) show that oxygen use is not beneficial for most people with chronic obstructive pulmonary disease (COPD) and moderately low levels of blood oxygen. It neither boosted their survival nor reduced hospital admissions for study participants. Previous research showed that long-term oxygen treatment improves survival in those with COPD and severely low levels of blood oxygen. However, a long-standing question remained whether a different group of COPD patients—those with moderately low levels of blood oxygen—also benefit. The study was funded by the National Heart, Lung, and Blood Institute (NHLBI)—a part of the National Institutes of Health—and the Centers for Medicare & Medicaid Services.
