A totally boring (in a good way) day for Zoe.  She is doing really great on CPAP.  She's sitting at about 30% oxygen and the doctors were able to durn down her nitric to 0.5.  Hopefully by tomorrow it will be off entirely.  Zoe just rested peacefully all day,  waking up occasionally to look around and then right back to sleep.  She had her best blood gas ever today.  It had a Ph of 7.3 and a CO2 level of 41, which means the carbon dioxide in her system is significantly lower and hopefully means that some of the shunting due to the pulmonary hypertension is slowly going away. We're keeping our fingers crossed.
