Sunday evening update to "Caleb has RSV"

They got his oxygen down to 1/4 liter this afternoon.  (They turned it down little by little and then waited to see if his numbers held steady.)  But we had to turn it back up to a 3/4 liter this evening because his heart rate jumped back up to the 200s and his oxygen went down to 88%.  (Actually, probably his oxygen dropped and then his heart rate went up as he tried to get more oxygen.)

I don't know much about this but I don't think we'll be going home tomorrow.   He has to be completely off oxygen for four hours and still doing well before he's ready to go home.
