2 embolisms
A Tale of 2 Embolisms. A friend & I suffered Arterial Gas Embolisms (AGE) almost exactly a year apart, on very similar dives, on the same boat, in almost the exact same location, while we were diving together. Both dives:
1) @185fsw 2) Back gas was air 3) Short bottom times because the anchor was dragging 4) No computer violations 5) Onset of symptoms within 3-4 minutes 6) Paralyzed on 1 side – his left, my right 7) Fully resolved on surface O2 within 30 minutes 8) We both walked up on the dock when we got back 9) Both took a level 1 chamber ride as a precaution 10) Both have resumed diving with no aftereffects A few differences: 1) My dive had 3-4 minutes bottom time; his was a true bounce dive 2) My ascent was slower due to the amount of scope on the anchor 3) I switched to 50% O2 @ 70fsw even though I didn’t need to as I wasn’t sure I could use the O2 hang reg because of the current. I was able to use it so I had quite a bit safety margin. Posted for information purposes only. Informed, thoughtful comments are welcome. |
