> These only seven dives to more than 300 m do not include the dives of professional saturation divers using a divers bell at constant pressure for the transfer from surface to ground and back. These seven dives are done with decompression in the water not using a divers bell and saturation diving.
The selected answer is talking about huge pressurisation changes in a short amount of time, that's a very different situation and nothing like what commercial deepdivers do.
Saturation diving involves weeks of adjustment in a bell.
Much of the science suggests we haven't even come close to pushing the physical limits but no one is willing to risk it, the world record was set 30 years ago.
Note that humans can and do work at higher pressures than this.
