Oxygen therapy is a medical treatment. It must be prescribed by a doctor. For people with COPD, oxygen therapy can be a helpful part of their treatment plan. The prescription your doctor writes will include: If you need oxygen for rest, exercise and/or sleep, and how much in liters per minute (lpm) for each activity.
Your health care team may send you to a specialist to see if oxygen can help you. Oxygen is only useful as a treatment for people with a low oxygen level. Itâs not a treatment for breathlessness, which in COPD is usually caused by difficulty moving air in and out as you breathe, rather than by a low oxygen level.
