Brody's condition has become worse since we got to Minneapolis. His o2 sats have dropped, so they tried hooking him up to nitric oxide. It is not laughing gas, which is Nitris oxide. Nitric oxide goes into the lung with the oxygen and gets down deeper into the lungs. If it is going to work, it immediately starts increasing the o2 sats. In Brody's case, it did not make a difference. His lungs sound clear and that is the frustrating part. There are clearly areas of the lung that are ciculating air and there are areas that aren't. There will be another chest xray this afternoon. Right now, the entire situation depends on time. He may get worse and he may get better. We do not know. If he starts getting worse, as in going downhill, things may happen fast and they will need to do the lung bypass machine. Or, he could slowly ride this thing out and recover. God only knows. We don't get to call the shots in this. I will be signing off for a while. The words lung failure were used today and that is breaking me.
