What I wonder though since Dr Beaver evaluated all the evidence and came to the conclusion that both Stewart and Sotis suffered from hypoxia, where the disconnect is with the computer graphs that were posted elsewhere. The poster, a lawyer who would know, stated that it could not be hypoxia. The graphs support that and show a rapid ascent and missed deco, as Dr Beaver also indicated in his autopsy report.
However, we are not being shown the crucial next graph, when he goes from a very slight downward trend in the PPO2 to the point where he physically dropped like a rock according to Dr Beaver. We don't know if he continued to breathe the loop at the surface and became hypoxic in the missing graph or if he removed the loop without closing the BOV and flooded the unit and sank like a rock or if he succumbed to DCS.
If we are to believe that both Stewart and Sotis suffered from DCS, how was Sotis treated with only O2? Or did he receive further unpublished treatment?
