Oxygen becomes toxic at two atmospheres or about 300 feet since it is 1/5 atmosphere at the surface. Nitrogen is dangerous at lower concentrations if the diver doesn't rise very slowly. It also become like a narcotic about that depth.It is possible to regulate the concentration and use helium and selected gases and you can go down to at least about 1500 feet. The pressure will never kill you because we are made of water which is not compressible. http://hypertextbook.com/facts/2005/Mich...itrogen is dangerous at lower concentrations if the diver doesn't rise very slowly.

But vertical forces are another matter, and it has everything to do with blood pressure. At sea level, or 1 G, we require 22 millimeters of mercury blood pressure to pump sufficient blood up the foot or so distance from our hearts to our brains. In 2 G's, we need twice that pressure, in 3 G's, three times, and so on.hile John Stapp showed that people can withstand much higher G forces than had long been thought, there is a limit to what anyone can take. Princess Diana tragically proved that. Experts estimate that, in the car accident that killed her, the G forces on her chest were about 70 G's (and 100 G's on her head).
