A serious case results in one DAN AP Member, a dive industry veteran of more than 30 years and a PADI Course Director, having to make the life-altering decision to stop diving.
MY INCIDENT
I was undertaking a long cavern dive with my new and never-been-dived-before rebreather with newly designed and neverbefore-used back counter lungs. During the dive I experienced cramps, so cut short what was going to be a two-kilometre expedition. Assuming I was dehydrated, I took a double dose of a rehydration product (thinking I was doing the right thing), which stopped the cramps.
I was on my fourth day and fourth dive. The plan was to complete a three-hour dive in the cavern system with the rebreather. I did all the usual pre-dive checks, including a pre-dive pre-breathing with the unit before descent. My buddy and I descended, checked our cells were working, and then switched to CCR. It took a few moments to orientate and get somewhat comfortable; but I never got completely comfortable and felt like I was struggling with the unit the whole dive. Something just didn’t feel right, and I put it down to:
1. A new CCR;
2. I had little time with a CCR since being certified two months before;
3. I had to spend time and work through each problem until I was comfortable. I had, over the past three dives, resolved a few small issues I was having.
At 55 minutes into the dive I seriously questioned if I could suffer three hours of this. After 60 minutes I started to inhale not only through my mouth but also uncontrollably through my nose. At 75 minutes I was so frustrated I had to do something; and that was to bail out of the dive. I bailed out to OC and almost immediately recovered normal breathing and felt better. I stayed on OC for a few minutes, and then knowing I was close to the exit, I switched back to CCR, and felt completely okay. We ascended and I was prepared to discuss with my buddy what had happened, with the intention of continuing the dive.

TECHNICAL DIVING TIMELINE (1660–1999)
It’s fair to say that the emergence of “technical diving” in the late 1980s, that is, the introduction of mixed gas technology, and later mixed gas rebreathers to the sport diving community, represented the culmination of hundreds of years of scientific discovery and technological development.
