Circulatory and respiratory changes during post-natal transition in a premature case (GA = 30 wk) with patent ductus arteriosus (PDA), in which pulmonary vasculature does relax but ductus arteriosus remains patent. Plots compare transitional dynamics in delayed cord clamping (DCC, solid lines) against immediate cord clamping (ICC, dashed lines). Comparison of oxygenation in ICC with DCC is seen in a for CA and PA. Pulmonary flow rate is higher than normal premature birth by 44% as seen in b. Axis ranges are the same as Fig. 3 in order to facilitate comparisons between healthy and PDA cases. CA: carotid arteries, PA: pulmonary arteries
