What are the side effects of oxygen therapies?

Oxygen therapies don't cause many side effects. Supplemental oxygen therapy may cause a dry or bloody nose, skin irritation, morning headaches or fatigue. During hyperbaric oxygen therapy your ears may be uncomfortable and need to "pop" due to pressure changes, and afterward you may experience a few minutes of lightheadedness. If you start to have symptoms, such as anxiety, headaches, blue lips or fingernails, confusion, restlessness, drowsiness, anxiety or breathing trouble, these are not side effects of oxygen therapy. These symptoms indicate that there is a problem with your oxygen supply and you should contact your doctor. Serious side effects that may be caused by changes in air pressure or too much oxygen include: vision damage, hearing loss, organ damage or seizures. Talk to your doctor about signs of these problems and how to avoid them.
