What does Oxygen Therapy involve?
Oxygen therapy involves administering oxygen at a concentration which is higher than that found in air, in order to treat or prevent symptoms and onset of arterial hypoxemia. This form of treatment can be applied in acute onset situations, for the amount of time needed to overcome the acute event, or in the longer term when the patient has a serious, stabilised form of chronic hypoxemia.
In detail, long-term oxygen therapy is given to patients with Chronic Obstructive Pulmonary Disease (COPD) as it has been proven to significantly increase survival rates, quality of life and neuropsychic performance, whilst at the same time reducing the number of days of in-patient care and associated hospitalisation costs. Its use has also been suggested for treating diseases other than COPD, such as interstitial lung disease, pulmonary arterial hypertension, cystic fibrosis and even for palliative purposes.
