We saw the doctor this afternoon, and there are some good signs. They gave him a dose of surfactant (a soapy substance in the lungs that helps prevent the alveoli from closing), and he immediately was able to start breathing room air (normally, premature babies are on high levels of oxygen for quite awhile after birth). The doctors were quite surprised that he was able to transition to room air so quickly. His heart is strong and his blood gas levels look really good.
