COPD is now the third leading cause of death in this country, surpassed by only heart disease and cancer. What’s more, 2014 marked the 11th year in a row that more women died from the disease than men. While smoking remains a primary risk factor for COPD, air pollution, secondhand smoke, exposure to workplace dust and chemicals, heredity, a history of childhood lung infections, and socioeconomic status also play a role in its development.
That every person with COPD will eventually need supplemental oxygen (also known as oxygen therapy) is a common misconception among COPD patients and their families. According to the American Lung Association, oxygen therapy is needed in COPD when lung function is reduced to such a degree that it interferes with normal bodily functions and the ability to maintain or increase activity.
Although some may balk at the thought of using supplemental oxygen, current research tells us that it has many benefits, including:
Oxygen is considered a drug and therefore requires a prescription from a qualified healthcare professional before being prescribed. Moreover, prior to your provider issuing a prescription, certain criteria must be met that should be based upon well-established guidelines.
Although some gray areas remain as to which patients benefit most from supplemental oxygen, the American Thoracic Society recommends long-term oxygen therapy (LTOT) for the following:
As mentioned above, there are some groups of people with COPD in which the benefits of supplemental oxygen remain unclear, but who may benefit from receiving oxygen therapy at certain times or under certain conditions. This includes COPD patients:4
In 1980, the Nocturnal Oxygen Therapy Trial (NOTT) compared the efficacy of 12-hour nocturnal oxygen (used only at night) with that of 24-hour oxygen (used continuously). 203 patients with hypoxic (low oxygen) COPD were followed for at least 12 months and randomly allocated to either continuous or nocturnal-only oxygen. Study results concluded that continuous oxygen therapy was associated with a lower risk of death from COPD than was nocturnal-only oxygen.
Whether nocturnal-only or continuous flow, your health care provider will use their clinical judgment and the results of your physical exam and laboratory tests to determine if you’re a candidate for Long-Term Oxygen Therapy (LTOT).5 To find out if you qualify, talk to your health care provider as soon as possible.
