I have started deeper diving (below 130) and I have learned that I suffer from hypercapnia. Retention of CO2. Some of my instructional books say that some people are just more prone to CO2 retention. Is there a way to find out, a test that would indicate that I have this build-up moreso than others? I had some difficulty in the 120-130 rang a few years ago, under exersion, rapid decent and depth, I became highly anxious. It has taken me several dives to regain my confidence in the lower limits of recreational diving, regulating my breathing and exhailing forcefully. I realize that learning to extend my range, I will need to begin tri-mix, but at around 165, I begain feeling the anxiety and nausia again. Is this normal? The other divers I was with expressed no ill feelings and were at 180 (for a few min.) How does trimix and hypercapnia work? If I am predisposed to CO2 retention, is trimix going to solve that problem, or is is going to be something of greaster concern for me at greater depth?
Thanks
