While the majority of newborns transition from fetal to postnatal circulation without significant difficulty, it is estimated that 10% require some degree of resuscitation in the delivery room and about 1% require significant resuscitation.1 Birth asphyxia accounts for approximately 23% of the 4 million neonatal deaths per year.1 Delays in establishing effective cardiorespiratory function may increase the risk for hypoxic-ischemic cerebral injury, pulmonary hypertension, and systemic organ dysfunction. Some of these injuries may be preventable with prompt resuscitation. However, some of these outcomes are related to events or exposures that precede the birth process, such as prenatal injuries, abnormal development, and insults to the intrauterine environment.
