Summary
Birth, and the ensuing stress of newborn life, requires the heart to dramatically increase its level of functioning. Understanding how this process occurs remains a key problem as the heart lacks any ability to increase its level of functioning immediately before birth. Failure to effect this increase in heart function promptly at birth has serious implications for the well being of the newborn and represents a major problem in newborn medicine. Of the 250,000 babies born each year in Australia, ....Birth, and the ensuing stress of newborn life, requires the heart to dramatically increase its level of functioning. Understanding how this process occurs remains a key problem as the heart lacks any ability to increase its level of functioning immediately before birth. Failure to effect this increase in heart function promptly at birth has serious implications for the well being of the newborn and represents a major problem in newborn medicine. Of the 250,000 babies born each year in Australia, as many as 5,000 require intensive care primarily for cardiorespiratory complications. Accurate diagnosis and effective treatment of these infants demands knowledge of the normal heart adaptations that accompany birth, adaptations that are critically linked to the way in which the heart and the lungs interact. This project investigates how interactions between the heart and the lungs determines heart function throughout life. By understanding this process we will provide essential information that will aid the diagnosis and treatment of sick neonates undergoing intensive care.Read moreRead less
