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.
Some diseases and conditions that may require short-term oxygen therapy are: 1  Severe pneumonia. 2  Pneumonia is an infection in one or both of the lungs. 3  If severe, the infection causes your lungs' air sacs to become very inflamed.4  This prevents the air sacs from moving enough oxygen into your blood.5  Severe asthma attack.our doctor may recommend oxygen therapy if you have a low blood oxygen level. Normally, your lungs absorb oxygen from the air and transfer it into your bloodstream. Some acute (short-term) and chronic (ongoing) diseases and conditions can prevent you from getting enough oxygen.
