Medscape Medical News: Breathing Enriched Oxygen May Improve Major Depression

Numerous PET imaging studies have documented diminished brain mitochondrial function in patients with depression or schizophrenia. And mitochondria need oxygen to do their work. Yet, the idea of administering enriched oxygen in an effort to boost mitochondrial energy metabolism has long been viewed with skepticism – even though it's a simple and well-tolerated intervention – because of the fact that 90%-95% of the oxygen supply is carried bound to hemoglobin, and oxygen enrichment doesn't further increase hemoglobin saturation in individuals with normal lung function. However, recently it has been shown that inspired enriched oxygen roughly doubles arterial oxygen tension, and while this doesn't translate into anything close to a doubled oxygen supply to tissues, it may result in increased oxygen diffusion into brain tissue, the psychiatrist explained.
