On Monday, Granny was breathing on her own for about 9 hours. Tuesday was similar. Yesterday, she was only off of the ventilator for about 5 hours because, even though her heart rate was OK, they ran a test on her bad gases and it turns out that when she breathes on her own she doesn't exhale enough of the gases that she's supposed to.
"But he said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.' Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me. That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong."
~1 Corinthians 12:9-10
