It's a low oxygen kind of day

Guess it's one of those days when reality sneaks back up on me... Lilli's o2 sats (amount of oxygen going to her brain) was only 70-75 this am. Her lips looked very purple right when she woke up so I checked her right away.... they started at 68 then went up to 75. Well, now I know she is ready for this surgery. If all goes as planned with this surgery her o2 should be close to 90% of even mid 90's.
