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.
Without the right amount of oxygen, the entire body will have trouble doing even the most basic of tasks. Therefore, for many, oxygen treatment for COPD is a must. With the use of supplemental oxygen, the lungs will be able to absorb more pure oxygen and distribute it to the rest of the body.
