Folks, if you could say a prayer for my uncle who is at
http://www.stanthonynorth.org/ trying to come out of his coma (heart attack a few days ago) that would be much much appreciated and severely needed... docs are seriously concerned about the state of his brain function... atm they are taking him off the breathing machine to see if he can start breathing on his own with sedation. The first time they took him off, he only lasted for 30 mins...

So sorry to hear.
Odd they would keep him on sedation.
You figure they would have a "bag of tricks" using common sense like trying it OFF sedation.
Then trying some kind of stimulation combination of physical and sensory.
And last jolt or two in different areas with the defibrillator.
