- kazinator 8y agoThat seems like a poor idea. https://en.wikipedia.org/wiki/Oxygen_toxicity https://en.wikipedia.org/wiki/Oxygen_toxicity
- Shish2k 8y agooxygen toxicity at sea level (1 atmosphere of pressure) would require a 140% oxygen mixture - it's only when you go to higher pressure environments (eg 10m underwater = 2 atm) that it becomes an issue (at 2atm, 70% oxygen is toxic; at 4atm, 35% oxygen is toxic, etc - regular air is 21% oxygen, which becomes toxic around 7atm aka 60m underwater)
- matt_the_bass 8y agoYou’re generally on the right track, just off slightly. In the scuba diving world 1.4atm partial pressure of Oxygen is generally considered the maximum safe partial pressure when working (ie swimming). 1.5 atm for rest. This makes the depth limit for regular air to be 216 feet. Though there are a lot of divers who dove deeper than that befor trimix became so common.
- dgritsko 8y agoWatch the TED talk linked elsewhere in the thread, there are many, many things he talks about doing that are also poor ideas.
