I think he gets out tomorrow. Chamber treatments are usually 2-6 hours. Some chambers are big enough for a hospital bed or two. I haven't seen the one he's at.

I have a PFO, and I don't get symptoms until I dive deeper than 110 feet. So, theoretically, I could still be doing shallow dives. But I also have AVMs in my lungs- arteriovenous malformations- where arteries go to veins with no capillaries in between, so bubbles that would normally get filtered out by the lungs go right through, potentially to cause trouble by lodging in the brain somewhere. If I only had the PFO, I would have had that fixed, which, for me, would have involved robot surgery and heart/lung bypass, but it would have been worth it- that's how much I loved diving.
