Update:
My father never ended up leaving the ICU yesterday after all.
Apparently he is losing blood. So, they think that he likely has internal bleeding. They took a CT Scan yesterday and are supposed to let us know the results some time today.
On the bright side, Father Waters from York, PA drove out and gave my Dad last Rites yesterday evening! 😇
(The SSPX wouldn't send one of their priests and suggested asking a novus ordo priest instead.)
