Mom is doing much better and she will probably be going home today. We are waiting for the doctor to assess the results of one last blood test and then discharge her.
Today we have had a barrage of professionals telling my mom what she can and can't do when she leaves here. Mostly what she can't: can't lift anything heavy, can't exert herself in any way for at least a couple of weeks, and can't be friends with Salt anymore. Apparently salt is bad at letting the body rid itself of fluids. And extra fluid is a dangerous thing. And mom's heart is pumping out fluid at a rate of 35% when it should be in the range of 65%. (That is the watered-down version, no pun intended, of what's going on...but I'm not a medical professional so that'll have to do ya.)
The good thing is that mom is already sensitive to the amount of salt she eats: no shaking it on her food and she really limits processed foods and eating out. A lot of us would have been more than a little disappointed to learn that salt in our lives was virtually banned, but I think mom will handle it just fine.
