Emma, Lodi High's valedictorian for the class of 2011, had been waiting nearly two years for a lung and liver transplant. That surgery happened Saturday and a much less complex follow-up operation was Monday. 

Those are the basics. Cathy Huckaby, a nurse, close friend of the Greene's, and all-around terrific gal, shared the following info., which includes more detail:

This is what I just posted on facebook:

I just got off the phone with Hayley (her mom)...Emma is now off the ventilator & breathing on her own (with a wee bit of Bipap-Oxygen). She has only 2 IV's now (several have been taken out), and she was able to have some crushed ice this AM...all kinds of progress! She's talking w/ her parents, and asking about people and how what exactly happened to her the last few days. She is taking deeper breaths and getting used to her new lungs.(!) Her incision is healing well (she only had one long one). Being the tough gal that she is, she doesn't ask for pain medication very often...(she has a PCA Patient Controlled Analgesia) so she can push a button and get excellent pain meds IV for quick relief). She can move her arms and legs weakly...strength is coming back slowly and she tried to scoot herself up in bed this morning. Her parents Mic & Hayley are spending every minute w/ her and Stanford has generous visiting hours... they of course are weary, but very encouraged with this progress. They moved from a local hotel to the Ronald McDonald house, which is only $10 a only a night (!) There is a window in her ICU room, and they can see black squirrels & birds from it. So great news all along the way.
