Long-term oxygen use not beneficial in some patients with COPD

KEY POINT

Use of long-term supplemental oxygen therapy in patients with chronic obstructive pulmonary disease (COPD) who had blood oxygen saturation levels between 89% and 93% at rest or less than 90% during exertion did not result in improved outcomes or prolong life, according to results of the Long-Term Oxygen Treatment Trial (LOTT) published in the New England Journal of Medicine.
