Got this email from my FIL ...
I dropped Mom at the hospital early this morning and went in to see Grandma for a short time. They have replaced the stomach drain tube with a smaller feeding tube. When I left a respiratory nurse was beginning a two hour test to see if they can take her off the ventilator. The start of it appeared to me to be going well.
Grandma is very alert but of course cannot speak because of the tubes. She recognizes everyone and waved goodbye to be me as I left to go to work.
That's all I know at the moment. Will keep you posted.
