Update

In the waiting room at Children's, while D and her dad are inside with Andrew. He's doing well....his volume has moved up just a bit to 27, but they're not concerned at all. They'll probably try to keep it pretty stable until about 8 hours before the surgery, to give him the maximum opportunity to heal.

He got an "oxy challenge" this morning, which is a test to see how well he'll respond to oxygen in his lungs. They turn up the ventilator to 100% and check the oxygen saturation in his blood....if it goes up, that means his body knows what to do with the oxygen and that he will probably respond well after coming off the ECMO. The results: his numbers went from fifty-something to over three hundred....a very positive sign.
