Home oxygen therapy in Denmark.

Home oxygen therapy is an acknowledged treatment for patients suffering from chronic hypoxaemia, due to pulmonary or cardiac disease, and may have positive effects on survival and quality of life. The risks and side effects of the treatment are usually mild, and the equipment has developed to become relatively affordable, accessible and easy to transport. Adjustments in the oxygen settings can be necessary when travelling by airplane or during physical effort or sleep. Prescription and follow-ups are usually best maintained by hospital departments with expertise in pulmonary medicine, as argued in this review.
