As the lungs aerate, pulmonary vascular resistance falls, blood flow through the lungs rises, and fetal circulatory pathways begin functionally closing. Most term newborns accomplish this newborn cardiopulmonary transition with drying, warmth, positioning, and observation rather than […]

The term describes a care framework rather than a guaranteed sequence or an exact stopwatch interval. Some families have […]

A major physiological transition for the newborn Birth requires a newborn to move rapidly from placental support to independent breathing and circulation. With the first effective breaths, the lungs expand, fetal lung fluid begins to clear, and pulmonary blood flow increases. Circulatory pathways used before birth start to change as the baby adapts to receiving […]
