7:28AM Tia finally got some rest last night, she slept in 2 hour increments from 11:00 until 5:00. Her nurse was very quiet each time she came in and kept the disruptions as gentle as possible. Tia's Oxygen Saturation in her blood (O2 sat) dropped several times last night in the 80% (she was 98-100% in the ICU). The 80's are not dangerous, however the fact that there were trends of the numbers dropping are concerning. At 5:00 we brought her down to Radiology for a x-rays of her chest to look at her lungs. The x-rays didn't show any fluid around her lungs, which is good, but the x-ray cannot pick up any small collapses in the lung. The doctor that just came in said that he thinks she may be experiencing small collapses. Tia was excited to hear that she was on TV last night and wants to see the video clip. She tried to wake up about 20 minutes ago but she fell right back to sleep. Poor kid is really tired
