Pittsburg, Kansas | Yes. The rebreathers use oxygen so as to not produce bubbles that normally come along with breathiing regular air. And that is where the oxygen toxicity comes into play.
Breathing air it comes into play at something around 200 ft depth. Breathing 32% nitrox it comes into play at something over about a hundred feet depth. Breathing pure oxygen at one atmosphere or 33 ft depth you are dead as it becomes the equifilent of breathing pure oxygen at double concentration. Oxygen toxicity.
Yet on another note cancer treatments have been found to be very helpful by administering hyperbaric oxygen treatment (higher oxygen concentrations but still under toxicity levels) to cancer treatment patients. Hyperbaric oxygen is used regularly and has been for a long time for severe burn victims treatment. Causes healing to be much faster.
I just tell people I am getting my hyperbaric oxygen treatment when I dive nitrox at around 100' depth for a while or air at quite a bit deeper depths. LOL | |
