Abstract:Introduction
Advances in neonatal care improved the survival of very prematurely born infants. Exposure to high oxygen is often necessary to ensure adequate oxygen uptake in these infants, leading to halted development and oxidative injury of the pulmonary vasculature which is often accompanied by increased pulmonary arterial pressure (PAP). Although pressures normalize in school age childhood, various stressors as hypoxia and exercise may unmask increased pulmonary vasoreactivity. Furthermore, now that these … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
