An update from Melissa today:
Yesterday the doctors were able to successfully replace the tube that went into William's stomach (the arterial line), and it's working! Praise God!!!! They received a blood gas test back, oxygen levels are still low, but carbon dioxide levels were good.
This morning: William is being switched from the other breathing machine, we need him to get better oxygen saturation so we can bring him down from the 100% oxygen. Pray he takes to the new machine and pray they can bring the oxygen down. Pray his body receives the oxygen it needs to heal and survive.
