Breathing not getting any better

When I came in today the nurse told me that Avery was having a lot of periodic breathing as well as apnea, where she will stop breathing and then take a big breath. Doctors are not to happy with this, they were hoping the breathing issue would get better or at least stay the same. They are now looking to see if there is an infection. They have started her on another antibiotic (now she is on three), they are going to draw blood, collect urine, and take some cerebral spinal fluid from her head. She is scheduled to have a sleep study done on tuesday so they want to rule out everything. The sleep study will do no good if the breathing problem is caused by infection.
