The Long-Term Oxygen Treatment Trial

The National Heart, Lung and Blood Institute (NHLBI) and the Centers for Medicare and Medicaid Services (CMS) today, announced the publication of the long awaited results from the Long-Term Oxygen Treatment Trial (LOTT) in the New England Journal of Medicine.

Long-term oxygen treatment has already been shown to improve survival and reduce hospitalizations in those with COPD and severely low levels of blood oxygen (i.e. if your saturation rate is equal to or less than 88 percent at rest). Oxygen treatment may also be prescribed if COPD patients have a “moderately low” oxygen saturation rest that falls below 90% with activity or when sleeping. Until now, there was little research that told us whether or not oxygen for this moderate group with moderately low saturation levels at rest (between 89-93 percent) and below 90 percent with activity was beneficial.

LOTT enrolled 738 people with COPD who had moderately low oxygen saturation levels at rest or during activity in a randomized clinical trial where half of the group was prescribed oxygen treatment and half was not. The study found that on average, the patients who were prescribed oxygen treatment received no additional benefit to survival, hospitalizations, worsening symptoms or to quality of life. That means that based on this study, for most COPD patients with moderately low levels of oxygen saturation, oxygen use is not beneficial. At first glance it is easy to be surprised by these results, especially as it relates to those patients who use oxygen during activity. You may fall into this group and find it hard to imagine getting on that treadmill in the morning to get in your steps without sliding on your oxygen.
