Natty, does she have a Medical Directive in place to let her wishes be known should the next step be a ventilator--yes or no? Also should have a directive about tube feedings. In general, would she want to be kept alive by artificial means? I hope this has already been decided, as it's a hard and emotional decision for the family if this isn't in place.
As Mary stated, sometimes people do come back from the very brink--just as her husband, David, Rick, and I did.
Hugs,
Connie
