Is this the same thing as scuba diving? And if so, can we look at the medical history of scuba divers to see the relative prevalence of Alzheimer’s?

- pivo 5y agoScuba divers don’t breathe pure oxygen, so that’s one difference
- nradov 5y agoScuba diving oxygen exposures are much more limited. Most divers still breathe compressed air, so a typical dive to, let's say, 66 ft / 20 m would only cause an oxygen partial pressure of 0.63 ATA. Some of us do go deeper and use mixed gasses with more oxygen, but we carefully limit oxygen exposure to ensure safety. Acute oxygen toxicity can cause a seizure which is usually fatal underwater. So we never go above 1.6 on the oxygen, and then only for brief periods.
