What happened to the eye bubble test?

[DandyDon]

I read somewhere a year or two ago maybe about pulling your buddy's bottom eyelid down and looking for bubbles in the crease - but nothing since. Just searched here and DAN, but couldn't find anything...??

My TDI Inst teaches to do this and if either of us have 3 bubbles, get on oxygen. Anyone know anything more?

I have never heard of such a thing, and I've had two different hyperbaric docs mess with me. So either it's brand new, or obsolescent.

Found it. Couldn't find it with the SB Search, but with a Google search of the web, came back to this forum: Bubbles Under Eye Lids here. It's even older than I thought, tho - was looking for more recent and comprehensive info.

2002 ain't old; shoot that's pretty recent. Due to the comments made by Doc Deco, it looks like you'll need a bit of training to check for this, and the symptoms are brief. I probably never heard about it 'cuz it doesn't seem all that useful.

We checked each other last weekend. I had one bubble one time, none the next. Didn't see any on him. But then, we were diving only 1 minute into deco on Navy air charts, but diving Nitrox for an edge, then doing more than the required stop.

In practice, only good vision should be needed, not a magnifying glass. May not be proof of safety, but if I ever do see 3 bubbles - Oxygen and a DAN phone call at least.

It was an observation made a few years ago by researchers who were bending snakes for somethingorother... Bent snakes had visible bubbles in their eyes and at the time people speculated that it could be a good field-diagnostic for divers. IIRC it had something to do with counting bubbles in teh eye-lids....

R..

PS....there I go again. Don already dug it up....

The link said between 20 and 30 bubbles...

If proofed this should be a very useful resource for those middle of nowere dives.

Last month I was diving on a lake that was a good 3 hours chopper ride from the nearest chamber. A diver surfaced from 100 feet in less than 30 secs cause by an OOA emergency, luckly he didn´t got bend.

My TDI Inst taught to look - if 3 or more bubbles visible to the naked (or corrected) eye observer - get on O2, at least.

Yep, indeed - would have suggested O2 anyway. I hope he sit out 24 hours...?

 

[RP_Diver]

We made him SIT for 24 hours and have him under close observation for that period...

I must say that we made him sit because he wanted to jump in for the last dive of the day.......

At that point I made a mental note to self.... Never dive with him again.
