i'm on a plane in 2 hours. the update so far is that her system has been flushed of old medication and they have given her a new drug that has stabilized her blood pressure. she is now responding to physical stimulus, but still can't breathe. they are giving her until tomorrow afternoon to show marked improvement and at that time will detach her from the machine and see what happens.
