This evening Liam seems to be responding to the new ventilator and the blood pressure medications (they're having to keep the blood pressure in his lungs lower than the pressure in the rest of his body) but he now has pneumonia, too. They're having a difficult time treating the condition he has because it's typically seen in full-term babies where they can do heart/lung by-pass to cure it, but he's too little for the bypass machine. They said his situation is really unique and they just don't ever see this issue in babies as young as Liam. They called St. Louis today about trying a treatment on him they typically use on older infants but St. Louis said they don't typically use it this young and that it'd be a last-ditch effort. If he stops responding to the current blood pressure meds, there's one more blood pressure medication they can try, then this other treatment would be the next option. The next couple of days are critical.
