We went back down awhile ago to see Liam. Apparently, after we left earlier, they had to again put him on 100% oxygen again and by the time we got back to visit again, he was back down to 85%. They said he's been extremely unstable today. Anyway, we had to leave the NICU b/c they are putting him on a high frequency ventilator right now to try to minimize the damage to his lung tissue...after they're done and have him settled back in and get a chest x-ray, they said they'll let us back in. I also forgot to add earlier that they had to give him a blood transfusion because he became anemic.
