A minimal threshold of brain oxygen delivery (rSO2>30%) may be required for cortical activity. These data raise questions regarding assumptions of irreversible brain damage with prolonged CPR, as well as the possibility of consciousness and cognitive activity during CPR.“
In my opinion NDEs are significantly demystified at this point. I’m reminded how often NDE proponents have made the exact opposite point regarding cortical activity.

If you are going to make statements like that, Sbu, you're going to have to back them up. These are the facts about Parnia's poster.
1. A small percentage of patients (was it about 5%?) were noted to have some alpha waves during prolonged CPR
2. These were measured by placing a monitor on the patient's forehead (or further up) during breaks in CPR according to Parnia's video presentation. If there was any movement of the patient's head during the brief measurement period then that could produce a false reading (correct me if that's wrong, but one of Parnia's colleagues asked about this). In other words, the waves could be an artifact. But they might not be., of course
3. Parnia hasn't told us if the alpha waves overlap the reported NDE's. You are assuming they do. Why ?
3. The study hasn't been completed. Let the experts analyse it before drawing conclusions.
4. Even if the alpha waves overlap/coincide perfectly with the NDE's, it could only potentially explain
some of the features of NDE. It cannot explain
all the features, particularly observations out of the potential range of the patient even when their eyes were open. If you want to assume or pretend that it does, then you are kidding yourself and that's not sound scepticism.
5. We have many OBE's/NDE's on the record where no CPR was involved although deep NDE's were reported.
Al Sullivan. Pam Reynolds. Denture man. Lloyd Rudy's patient. Michaela Rosa. Monica Williams. The list is long.
Just take Al Sullivan, that's enough to make the point, surely. Keep your new 'weapon'...CPR induced brainwaves... handy. Al was under general anaesthesia, undergoing open heart surgery and was isolated behind a raised drape to block any potential view of the operation or the medical personnel doing their work.
He saw the surgeon flapping his arms, amongst other important details such as seeing his leg cut open (to provide a vein for the by-pass).
Could you specifically explain how some alpha brainwaves (which he would certainly not have had) explains this case ? I'm (personally) getting pissed off with what I consider just plain opportunism without any reason other than...well it sounds plausible and Linda (who is not an honest sceptic) is pushing it, so I may as well weigh in my two cents.
If you can't, then would you please stop repeating the same claim that NDE's have been (significantly) demystified. They haven't. Not even close.
I don't see Parnia and his colleagues abandoning the study. If they thought that some alpha waves in a couple of patients had explained the mystery, why on earth are they continuing ?
