I am not going to opine on what this guy did or did not see. I just want to comment on you post re: stopping circulation & a bypass machine.
There are a few cardiac procedures that require complete cirulatory arrest. Meaning, the bypass machine is turned off & the hear is stopped and drained of blood. I have provided anesthesia for these cases numerous times. We do everything to prevent brain dmamage. The body temperature is often lowered to about 17 degress Celsius, the head packed in ice, and high-dose benozdiazepines given. It’s a technique called “deep hypothermic ciruclatory arrest”. It is quite possible that this gentleman underwent such a procedure.
Do I believe in purgatory? Absolutely. Do I think this guy saw it? Who knows?
Forgive all the typos. I’m trying to hurry since I’m on my break at work.
If someone says they had such an experience, I have to believe they had such an experience...I cannot call them liars...I told a friend one time( when they were telling me about something they experienced and didn't know what to make of it.). I believe you had such an experience, that's all I can say...(it was about her father that had died a few years earlier).
One can choose not to believe them, but cannot say they are lying. Belief is a choice one way or the other...
Interesting post. I had surgery on my aortic valve and ascending aorta seven years ago. I’m told that in addition to the techniques you list, the doctors also used reverse perfusion (pumped oxygenated blood in the reverse direction to maintain oxygen supply to the brain). I’ve had no symptoms of “pump head”.
After reading your post, I did some research on the net regarding the neurological phenomena that can occur as a result. Most people don't remember anything, but those who do often have hallucinations which, as with dreams, are based on bits of information we've garnered from elsewhere. Sometimes they are religious in nature, sometimes they are not.
I did read of a few instances where people could report things that happened in the operating room while they were in circulatory arrest. Clearly, the brain does not stop working, and the person is not dead.
