So our little princess Katie is still on oxygen. She oxygen levels are up and down. We have an appointment on Friday to have a bubble echocardiogram. Because Katie is so small and she will need an IV, they will sedate her and take a look at her heart. The Pulmonologist thinks with her oxygen level up and down there may be a problem with her heart so he is looking to hopefully rule that out. She is over her cold which is definitely a plus and she seems fine but machines say otherwise. Only time will tell. I am praying we get good results and this is just a carry over from her cold and nothing more serious.
