She was taken to an ER where a desperate effort was made to revive her. It's not like they gave her a physical.
Desperately trying to revive her?
When she was brought in her heart was beating and she was breathing so what were they desperately trying to revive her from? A comma? All they knew initally is that she was unconscious. From there they set about doing a physical to determine why she is unconscious.
They especial look for trama as well as run all kinds of blood work.
From their physical it was determined that her heart had stopped beating for some reason, causing lack of oxygen to flow to her brain, causing her to be in a coma, thus causing permanent brain damage, ultimately causing her to be PVS.
I said what I thought needed saying. You replied that you weren't "buying it." I'm perfectly content with that, and in return, I didn't find any interesting research or theories in your posts. There's nothing more to discuss.
