Well, apparently the pneumothorax has cleared up but there is something new.
He has neonatal pulmonary hypertension that was revealed by a sonogram. Now this is a normal condition while he was in the womb; the gas exchange occurs in the placenta, not in the lungs. But once he starts breathing on his own, not good.
The doctors state it is not a real serious condition (it could be worse - requiring surgery) but we are still waiting to see when he can come home.
He has the most amazing head of hair I've ever seen on a new born.
