Since we arrived he has stayed somewhat steady at 70% oxygen, with his oxygenation staying in the low 90's. It looks like we are on a road of extremely slow progress back towards his baseline. Alisha and I are starting to identify nurses which we like and those we don't, based mainly on how quickly they react to Roscoe's ups and downs. It is a comforting thing to be able to leave him with a nurse that we trust. When Roscoe has a nurse that doesn't react very quickly then it troubles us to leave him alone for fear that she will fail to give him the support/care that he needs when he needs it.
PS: I apologize for the late update, the wireless internet access here at UCSF has been pretty horrible today.
