So this is Max after the first time he got his NG tube and O2 out of his nose. Isn't he so cute!! About 3 hours later, I was feeding him a bottle and he desated down to 65 and started turning blue. Scared me to death!!! Needless to say, they put the tube back in and the O2 on again. We found out that the problem was that his crits were too low, so the Dr. decided to put him on an iron supplement, and a few days later we were able to remove everything again and he's held his own ever since.
