I talked to my mom this morning. It sounds like Grandma's fluid balance got way off and she developed pulmonary and pericardial edema (fluid around the lungs and heart.) She is responding well to treatment and is in excellent spirits -- when my mom was getting ready to pick up some of her things from the farm, she told my mom to bring her a nice outfit to wear home!
Mom says Grandma's not out of the woods yet, but I'm feeling optimistic. I hope her doctor manages to hit that fluid balance "sweet spot" again with her medication.
