Oct 24, 2016 at 7:46 | comment | added | Luaan | Hyperbaric oxygen therapy isn't safe for a healthy person! Oxygen is very toxic, and a brutal oxidising agent - it's dangerous enough breathing it at standard pressure (oxygen radicals are one of the main causes of genetic damage), and it only gets worse at higher partial pressures. HBOT is used on people who have some trouble with normal oxygen absorption - for example, due to embolism or carbon monoxide poisoning. Those problems make it harder for oxygen to attach to red blood cells, which means you need a higher partial pressure of oxygen to keep the blood oxygen content proper. | |
Oct 24, 2016 at 7:19 | comment | added | MSalters | Not mentioned so far, but for long operations underwater you can use rebreathers. They work by recycling the nitrogen, scrubbing the CO2 and replacing it with fresh oxygen. Complex and risky - it introduces a whole new set of failure modes. | |
Oct 23, 2016 at 15:29 | comment | added | Makyen | There is a vast difference between what is considered safe when directly under the care and observation of a doctor in a hospital (Hyperbaric Oxygen Therapy) using medical grade equipment and what is reasonable for unsupervised recreational diving. | |
Oct 23, 2016 at 15:25 | comment | added | Makyen | The amount of air-time which SCUBA tanks provide underwater depends on the depth at which you are breathing. This can be much less than 1 hour for deeper dives. The volume that is contained in your lungs does not change, but the pressure at which that gas is supplied depends on depth. Thus, the static volume of gas contained in your tanks will provide a lower number of breaths at deeper depths (higher pressure). The time which you can spend at a particular depth without the need to decompress is also dependent on the depth. | |

Oct 22, 2016 at 21:40 | comment | added | user1160 | You will be breathing the same air pressure, but it will all be oxygen. This will increase the amount of dissolved oxygen in your blood. It's a little bit analogous to putting a burning tissue into an atmosphere of pure oxygen, I would think. I don't know exactly what causes the toxicity, but I'd guess that it's related to that increased rate of oxidation. | |
