He has been on breathing treatments every four hours except at night (which would be a six hour stretch when he wakes in the middle of the night and ends up in our bed AGAIN) for about three months. He has an ear infection. He had one about six weeks ago. His oxygen level in the doctor's office this week was in the low 90's, which is stable but upsetting because he used to register at 100. We will see the pulmonologist again in two weeks to discuss what to do.
