The first breath for a newborn is the most difficult because it involves overcoming the resistance of fluid-filled lungs and transitioning to breathing air. During pregnancy, the lungs are filled with amniotic fluid, and the newborn must clear this fluid while simultaneously establishing the necessary pressure and airflow for effective respiration. The transition also requires the coordination of various physiological changes, such as the closure of fetal shunts and the opening of blood vessels in the lungs, making this initial breath a critical yet challenging moment for the infant.
