> Each patient was placed in a hyperbaric chamber for 90 minutes for five days a week over three months while breathing 100 per cent oxygen through a mask. The pressurised chamber allows more oxygen to be dissolved into the tissues and mimics a state of "hypoxia", or oxygen shortage, which is known to have regenerating effects. If your breathing oxygen at a higher intra pulmonary pressure you have both higher concentration and higher absorption of oxygen, so how can it create a state of hypoxia? Is it a typo and they mean hyperoxia? Or is it a typo and they mean a hypobaric chamber? I also couldn't find an actual link to the paper?
