Grandpa is home, came home yesterday afternoon. He "Talked them out" of keeping him one more night, they determined what must of happened,is his blood pressure had dropped low enough it wasn't able to keep enough blood flow to the brain to keep him conscious, and have given him a medication to keep his blood pressure from dropping too low, that shouldn't raise his blood pressure overall either. and were told w hat to do if it happens again as part of being safe. aka get his chair leaned back so he is lying down, get his feet lifted up above his head as much as possible .Though...>I admit I thought of the fact 'wait....low blood pressure.....did it get so low that it wasn't reaching his brain quite enough for consciousness?' the other day.....anyway, yeah, he is home.
