Not sure what is true in all this, will just report what I have been told and not verified:
Dad was moved to a Skilled Nursing Facility on Tuesday. He pulled out his feeding tube and was transported to the Hospital for it to be put back in. Enroute, he had a cardiac arrest. They revived him and put him on a ventilator. He is now in the ICU. They will be removing this as he has a hemorrhage in the brain. The doctor reported that he doesn't expect him to make it through the night.
Please be in prayer that if this is truly Dad's state that he may go quickly and peacefully.
