I've been canned a few times on sat dives. Not fun, let me tell you. You sort of get used to it after a while...until your buddy ate beans before the start-OMFG!!!! But corned beef and cabbage with a side of cucumbers and broccilli is a suitable revenge.

Anything like an MRI? Cause I had one that lasted an hour once (halfway through they had to restart because I was moving my head too much)

There are a few small cans that are just a little larger than a MRI in dia., but those are usually theraputic: no more than 3ATA, usually 2.5ATA. No space for a tech so in those you are hosed if something happens. Most True hyperbarics for DCS are at least 4' Id and they go up from there. Mobiles are usually 5'-6' OD. The biggest I've seen was 9' OD and 25' long.

So an mri can be called worse than a chamber (if more so in size than in time spent)?

It all depends on your perspective. A MRI has openings at both ends-the chamber doesn't.

Ah, that is a good point. An MRI is there to tell you whats wrong though, not fix it. Also its loud as hell.

Don't mean to pry a lot navy, but what sort of situations caused you to have to go in a chamber? You mentioned sat. dives so i'm guessing that might mean tissue saturation?

Saturation diving: Your tissue will only hold so much nitrogen or helium. Instead spending a huge amount of time decompressing between dives, you stay at at depth or pressure until you finish the job and then decompress. A couple of divers made headlines in NY when they spent over 30 days on Heliox in a chamber between dives to fix som stuff on one of the water lines that supplies NY,NY.

I did a short stint and gave it up in favor of other endevours. Had a very enlightening "Come to Jesus" that made me re-think my carreer(s). I also had a few friends that talked unkindly about cans.

Never took a hit-don't want to either.

Well now Navy, you have peaked my interests, would you share your "come to jesus" event with us? ~Recon

There are several, but 270', working on a pipe, stupid young red neck thought it would be funny to cut lock-off tags from a pump, pump turned on and almost sucked us into the pipe. Dive over, 48 hours of deco and I left. They did fire moron and he got a slow boat ride back to the mainland so I wouldn't kill him when I got finished.
