Here are some pictures that WHM just posted here (the link might not work since it is Facebook).
Note the dinosaur face on the mask. Apparently this is theirs, and it helps Riley deal with his treatments.
Ryan helping out. This is earlier in the day when things were not going well.
It took all these people, equipment, and that ambulance to get him from Redwood City to Santa Clara! They have a pediatric intensive care unit there.
And this is later, when he was feeling a lot better. It sounds like they are going to start weening him from some of this tonight.
What a day.
That's it - move along...
