What is the deepest you can dive using special gas mixtures? What depth will crush the human body?
I don’t have a degree in any of this but it would seem that you could go down to any depth. If I am correct, the human body is made of about 70% water. This means that 70% of you body couldn’t be crushed. Then there is the other 30% though. But this should all be air space. This is the part that pressure would be able to crush, however the pressure on the outside is matched by the pressure exerted by the compressed gas you inhale from your regulator. But, I could be wrong about all of this, and please correct me if I am.
I belive the deepest any person has gone is 730 msw however this was a ‘dry’ run in a chamber using a hydrogen, helium and oxygen gas mix and the divers were not in a working condition as they where suffering from HPNS (high pressure nervous sindrome). The limit of conventional sat diving is around 650 msw but it’s very rare to blow down sat divers to that depth now as deep water rov’s can perform most tasks but every now and then you need a good old fashioned bubble head down there to do the work. As for crushing the human body you can irreblibly damage your ears if you don’t equalise them on the way down but I have never heard of anyone being crushed.
