enganging in advanced diving you will always come across to some symptoms to some degree. A lot of times one is able to "treat onboard" and get away with it. This in combination with an undoubtfully conservative deco settings does easily bias one towards a denial that something serious is in fact happening.One of the common-questions about this incident, is why they didn't pursue medical treatment earlier. I expect the answer is "because it initially looked like dehydration, and oxygen was just a precaution." When DT and DAN do the follow-up video, I'm certain we'll hear more about this.
At the moment, I'm inclined to suggest DT hasn't given us adequate information about the incident to point at any cause with any degree of confidence. It's tempting to want answers, but there's a risk of focusing too heavily on a single potential "red herring" and miss the actual culprit(s).
The delay in pursueing treatment is the least surprising for me in their whole description of events. I don't think they tyhought it looked like dehgydration and gave oxygen just as a precaution they gave the oxygen as a treatment, they just underestimated the severeness of the symptoms as such, whcih again is not uncommon at all (unfortunately), but I have to admit that I have been there as well.
I had been treating an inner ear DCS as late as 2 weeks after the incident and I even kept doing decompression dives in between. Not something I am proud of and certainly something I learned from, however I can totally see how that happened.
I think we have plenty of information and no it will never be a single red herring as you put it. But what has been described of the dive is plenty of reasons, why the outcome isn't even particularily surprising. There might be more infor, but I don't think it would matter too much.
What is more surprising is that DT did not expect such outcome at all which speaks a lot to their approach to conduct such dives being my major issue. And once more with the history of incidents they already have been involved apparently a very very slow learing progress if any at all
