UPDATE

The nurse just came in and said that Connor has dropped from a 17.1 mg/dL to 16.1 mg/dL (on a scale of 1-25). They have four zones of Risk:

Low Risk
Low Intermediate Risk
High Intermediate Risk
High Risk
Critical Risk

Critical Risk is from 20-25 and is where there is a high chance for brain damage to occur. Here's how Connor's measurements went:

40 hours: 15.5
50 hours: 16.9
62 hours: 17.1 (This is the point where they were getting a little stressed.)
74 hours: 16.1

The nurse said that if this trend continues, he would likely be able to come home without his glowing blue friend. So that's all good news.

Tiffany has been cleared to leave, but they said the insurance company will cover another day and she's welcome to stay, so we decided to do that. So it looks like we're here for at least (and hopefully only) one more day.
