I just talked with my dad and this is what he told me:
Granny is still quite weak, but her pneumonia is better than yesterday, though she still has a lot of lung congestion being suctioned out. Today the medical staff is much more actively working to test her to see if she's ready yet to breathe on her own so they can take out the ventilator. The congestion from the pneumonia may prevent that happening today but it appears they're making some real progress in that direction now. Praise God!
