Food and water is one thing...pressure is something else. Food and water will sustain them in the hole, but if they come up too fast from high pressure to normal surface pressure, like the old compression suit divers used to do when the suits would fill up, they can get the bends. It's buildup of nitrogen, I think, and causes amazing pain and sometimes death. That's more what I'm worried about. I remember they said the navy loaned Pennsylvania nine compression chambers. Now the question is are they going to have to use them. Is the pressure now equalized surface to underground? Has that been addressed tonight? They mentioned the drill was serving as a seal, so at that point it wasn't. That more what I want to know. Fox and CNN weren't saying before I came upstairs.

I thought I read a couple of posts earlier that stated the air pressure isn't an issue... Like I stated I don't know much about mining but with the two shafts and the water gone isn't the air pressure okay? My husband who is from KY and has had personal experience with mining states they should be okay ...

One of the persons interviewed is a specialist regarding decompression. He said that he and the equipment would stay for another 24 hours after the rescue is complete, just in case. So the rescue team is clearly taking into account all those possibilities.
