pressure on body

[gehadoski]

Dear all

I would like to know the max pressure the body can take, regardless of other factors, such as (Nitrogin Narcosis, oxygen toxecity,......etc).

Look for the depth records on scuba. That should give you a reasonable idea.

Two thousand feet is the absolute limit for the unprotected human body.

Not that I would want to test this.

Thanks a lot for your reply. I will never try that depth.

How would it be tested? Who came up with that number?
Can chambers go that deep?

Duke took some people to 69.5 ATA. That would be about 2260fsw.

The biggest problem seems to be how to keep the people breathing at such pressures.

I'm not convinced that you can support this figure scientifically. Theoretically, the solid or fluid portions of the human body are incompressible and therefore unaffected by increasing ambient pressure. The problems arise if gaseous spaces (middle ear, sinues, lungs etc) are not equalized to the ambient pressure. Again - theoretically - if equipment can be produced to serve a breathing gas at the appropriate pressure - (and this may be where the figure comes from?) you should cope at any depth.

As you increase the pressure, you increase the density of the gas your breathing, to the point where it's so dense you can't breath it. I'd imagine that's what dictates the limit.

I don't think anyone is claiming that assuming your airspace in equalised your going to implode at 2000ft or whatever.

I would be interested in knowing what happened to the structure of the bones at that depth/pressure :06:

. . . I don't think anyone is claiming that assuming your airspace in equalised your going to implode at 2000ft or whatever.

Would make a very cool video, though.
