Dear Dr. Powell:
I think I understand the physiology of what is going on in your attachment. Its been a while since I took A&P in college, but the venules (tiny veins) carry waste product, including Nitrogen (Im assuming only) out of the system. Apparently, from your attachment, microbubbles have a clotting effect, almost in a manner of the way fatty deposits can create arteriosclerosis. However, unlike arteriosclerosis, the microbubbles eventually clear themselves out, thus allowing the capillaries to fully function and carry nitrogen out of the body during off gassing.
The point of confusion in your attachment is there is no dive profile to reference it. For example, after the first dive, do I have the same blockage in the capillaries after a 21 ft. dive, as I would a 100 ft. dive? If so, how is that possible? There would be a whole lot more ongassing during a deeper dive.
And if the quantity of microbubbles is dependant on the dive profile, then I am wondering how, after only one dive, I had the dive alert symbol: Here is my first dive info:
SI: 43:20 hh/mm
Dive Time: 13:20 mm/ss
Max Depth: 24ft
Avg. Depth: 20 ft
When I did my SECOND dive, I had had a surface interval of 44 minutes, so how in the world after a 13 minute dive in 24 feet of water am I still getting a diver alert/microbubble warning? Granted, my SAC was very high that first dive (1.05), due to a strong current and aerobic sprint looking for the ledge (which I didnt find that first dive, hence the short time), but am I supposed to wait an hour after one 13 minute 24 ft. dive?
Thank you very much for helping me understand this. Its a little unnerving diving through alarms, but Id look like the biggest idiot in the world telling friends after one 20 ft dive, Sorry guys, go ahead, I have another hour before I can dive again.
